Transition risk has become a priority for adaptive policy and measures taken by firms in response to net zero emissions around the world. Internal Carbon Pricing (ICP) is an emerging set of practices voluntarily adopted by companies to respond to progressive climate policies and regulations. The main purpose of companies adopted the ICPs is to manage carbon risks, however, the literatures lack of discussion the linkage between the ICP and climate performance/carbon risk. This study identifies the climate performance indicators, including greenhouse gas abatement, cost savings, profit creation, and carbon risk management. This study also collects the data reporting from Carbon Disclosure Project (CDP, 2019) by Taiwanese companies for empirical analysis. The results provide the evidence that the ICP significant affects climate performance/carbon risk. This will encourage more enterprises to adopt the ICP for managing climate risk. Therefore, guidance of the ICP for transition risk governance aligning with TCFD are needed, and is recommended to ensure the climate resilience in Taiwanese enterprise. &nbsp

(−)-Anisomelic acid, isolated from Anisomeles indica (L.) Kuntze (Labiatae) leaves, is a macrocyclic cembranolide with a trans-fused α-methylene-γ-lactone motif. Anisomelic acid effectively inhibits SARS-CoV-2 replication and viral-induced cytopathic effects with an EC50 of 1.1 and 4.3 μM, respectively. Challenge studies of SARS-CoV-2-infected K18-hACE2 mice showed that oral administration of anisomelic acid and subcutaneous dosing of remdesivir can both reduce the viral titers in the lung tissue at the same level. To facilitate drug discovery, we used a semisynthetic approach to shorten the project timelines. The enantioselective semisynthesis of anisomelic acid from the naturally enriched and commercially available starting material (+)-costunolide was achieved in five steps with a 27% overall yield. The developed chemistry provides opportunities for developing anisomelic-acid-based novel ligands for selectively targeting proteins involved in viral infections.

Light triggers the formation of HNO from a metal-nitrosyl species, facilitated by an intramolecular pendant thiol proton. Two {FeNO}6 complexes (the Enemark-Felthan notation), [Fe(NO)(TMSPS2)(TMSPS2H)] (1, TMSPS2H2 = 2,2'-dimercapto-3,3'-bis(trimethylsilyl)diphenyl)phenylphosphine; H is a dissociable proton) with a pendant thiol and [Fe(NO)(TMSPS2)(TMSPS2CH3)] (2) bearing a pendant thioether, are spectroscopically and structurally characterized. Both complexes are highly sensitive to visible light. Upon photolysis, complex 2 undergoes NO dissociation to yield a mononuclear Fe(III) complex, [Fe(TMSPS2)(TMSPS2CH3)] (3). In contrast, the pendant SH of 1 can act as a trap for the departing NO radical upon irradiation, resulting in the formation of an intermediate A with an intramolecular [SH···ON-Fe] interaction. As suggested by computational results (density functional theory), the NO stretching frequency (νNO) is sensitive to the intramolecular interaction between the pendant ligand and the iron-bound NO, and a shift of νNO from 1833 (1) to 1823 cm-1 (A) is observed experimentally. Subsequent photolysis of the intermediate A results in HNO production and a thiyl group that then coordinates to the Fe center for the formation of [Fe(TMSPS2)2] (4). In contrast with the common acid-base coupling pathway, the HNO is not voluntarily yielded from 1 but rather is generated by the photopromoted pathway. The photogenerated HNO can further react with [MnIII(TMSPS3)(DABCO)] (TMSPS3H3 = (2,2'2''-trimercapto-3,3',3''-tris(trimethylsilyl)triphenylphosphine; DABCO = 1,4-diazabicyclo[2.2.2]octane) in organic media to yield anionic [Mn(NO)(TMSPS3)]- (5-) with a {MnNO}6 electronic configuration, whereas [MnIII(TMSPS3)(DABCO)] reacts with NO gas for the formation of a {MnNO}5 species, [Mn(NO)(TMSPS3)] (6). Effective differentiation of the formation of HNO from complex 1 with the pendant SH versus NO from 2 with the pendant SMe is achieved by the employment of [MnIII(TMSPS3)(DABCO)].

(–)-Anisomelic acid (AA), isolated from Anisomeles indica (L.) Kuntze (Labiatae) leaves, is a macrocyclic cembranolide with a trans-fused α-methylene-β-lactone motif. Cytopathic effect assays showed that the anti-SARS-CoV-2 effect of AA (IC50 = 4.3 μM) is comparable to that of remdesivir (IC50 = 2.1 μM), and more potent than that of molnupiravir (IC50 = 27.8 μM). Challenge studies in SARS-CoV-2-infected K18-hACE2 mice showed that orally administration of AA and remdesivir can both reduce the viral titers in the lung tissue at the same level. To facilitate drug discovery, we used a semisynthetic approach to shorten the project timelines. The enantioselective semisynthesis of AA from the naturally enriched and commercially available starting material (+)-costunolide was achieved in five steps with a 27% overall yield. The developed chemistry provides opportunities for developing AA-based novel ligands for selectively targeting proteins involved in viral infection.

Water security has become a priority for adaptive policy and measures taken in response to climate change around the world. This is an opportunity and a challenge for the Taiwan government to establish a climate-resilient water supply portfolio to ensure water security. This study incorporated the costs of water production, intermittency, and carbon dioxide emission reduction, as well as the currently available water sources and how they will be affected by climate change, and applied optimal control theory to establish a cost-effective model to plan a long-term (2031) climate-resilient water supply portfolio for Taiwan. The study then uses the Penghu area as an empirical case study for this water supply portfolio. The results showed that desalination will become the major source of water, accounting for 71.81% of the water supply by 2031. However, this high proportion of desalination water will result in a significant increase in the unit cost of water production and the carbon footprint. Therefore, water demand management is also needed, and is recommended to ensure sustainable water resources in the Penghu area.

Protons play an important role in promoting O-O or M-O bond cleavage of metal-peroxo complexes. Treatment of side-on O2-bound [PPN][MnIV(TMSPS3)(O2)] (1, PPN = bis(triphenylphosphine)iminium and TMSPS3H3 = 2,2',2''-trimercapto-3,3',3''-tris(trimethylsilyl)triphenylphosphine) with perchloric acid (HClO4) in the presence of PR3 (R = phenyl or p-tolyl) results in the formation of neutral five-coordinate MnIII(OPR3)(TMSPS3) complexes (R = phenyl, 2a; p-tolyl, 2b), which are confirmed by X-ray crystallography. Isotope labelling experiments demonstrate that the oxygen atom in the phosphine oxide product derives from the peroxo ligand of 1. Reactions of 1 with weak proton donors, such as phenylthiol, phenol, substituted phenol and methanol, are also investigated to explore the reactivity of the MnIV-peroxo complex, leading to the isolation of a series of five-coordinate [MnIII(L)(TMSPS3)]- complexes (L = phenylthiolate, phenolate or methoxide). Mechanistic aspects of the reactions of the MnIV-peroxo complex with proton donors are discussed as well.

Spin-orbit-torque magnetic random-access memory (SOT-MRAM) equipped with sub-I-V switching voltage [1, 2] is considered to be one of the promising candidates for next-generation low-power, high speed and non-volatile embedded cache memory applications. To fulfill these performance requirements, however, there are many technical bottlenecks to be conquered, such as SOT efficiency and scalability. This paper presents the recent progress on SOT-MRAM exploration of CMOS compatible high spin-Hall conductivity materials and structures.

Green growth is a global priority strategy for responding to climate change. This paper applies the OECD (2011a) green growth monitoring indicators framework to analyze 20 indicators of progress toward green growth specific to Taiwan. Principal Component Analysis and Analytic Hierarchy Process are used as weighting methods to calculate an aggregating composite index and perform sensitivity testing. The results show that for the past decade (2002–2011), Taiwan has been moving toward green growth but has been negatively impacted by its natural capital stock. This indicates that improving natural capital stock is a key for sustaining green growth in Taiwan.

A thiolate-bridged binuclear complex [PPN]2[(MnII(TMSPS3))2] (1, PPN = bis(triphenylphosphine)iminium and TMSPS3H3 = (2,2′,2″-trimercapto-3,3′,3″-tris(trimethylsilyl)triphenylphosphine)), prepared from the reaction of MnCl2/[PPN]Cl and Li3[TMSPS3], converts into a mononuclear complex [PPN][MnII(TMSPS3)(DABCO)] (2) in the presence of excess amounts of DABCO (DABCO = 1,4-diazabicyclo[2.2.2]octane). Variable temperature studies of solution containing 1 and DABCO by UV–vis spectroscopy indicate that 1 and 2 exist in significant amounts in equilibrium and mononuclear 2 is favored at low temperature. Treatment of 1 or 2 with the monomeric O2-side-on-bound [PPN][MnIV(O2)(TMSPS3)] (3) produces the mono-oxo-bridged dimer [PPN]2[(MnIII(TMSPS3))2(μ-O)] (4). The electrochemistry of 1 and 2 reveals anodic peak(s) for a MnIII/MnII redox couple at shifted potentials against Fc/Fc+, indicating that both complexes can be oxidized by dioxygen. The O2 activation mediated by 1 and 2 is investigated in both solution and the s...

Greenhouse Gas (GHG) emissions decoupling from economic growth are imperative goals for sustainable development. This study combines decoupling index and Log Mean Divisia Index (LMDI) to study which major transformation is required in the way energy is produced, delivered and consumed in order to achieve decoupling in Taiwan. The results indicate that a high-energy price can improve the energy structure by inciting energy efficiency use and result in decoupling CO2 emissions from economic growth. Targeting CO2 emissions through early action is the best approach to acquire decoupling. An annual energy intensity decrease of 2.4% is key for Taiwan to achieve absolute decoupling by 2020. The study suggests that the Taiwan government should focus on energy efficiency through investing in clean energy innovation at an early phase. Taiwan should consider national policies that are sensitive to effective economic strategies that enhance research and development and also invest in promoting energy efficiency in the economy-wide.

China is the largest greenhouse gas emitter around the world, and is committed to achieving an emissions peak by 2030. Although some studies have identified methods to project the emissions trajectory, they have disregarded the effect of abatement capacity of highly successful Clean Development Mechanism (CDM) projects (i.e. abatement knowledge stock) over the past decade. In addition, the literature lacks evidence to justify results, with several questions, such as when the emissions peak will be reached and how much carbon will be emitted at the peak, remaining unaddressed. This study introduces both theoretical and empirical model for estimating the greenhouse gas emissions peak in China. The findings revealed that there is potential to reach a carbon emissions peak, estimated at 117.70 MtCO2e, by 2028. The policy implications indicated that carbon pricing and the nation-wide Emissions Trading Scheme are the most important instruments to facilitate energy transition and clean coal technology (i.e. carbon capture and storage) development. This implies that the carbon price and carbon abatement investment may need to be greater than US$32.5/tCO2e and US$57,370,000/year to meet Paris Agreement goals by 2030 in China.

A novel type of silicon material, p-type quasi-mono wafer, has been produced using a seed directional solidification technique. This material is a promising alternative to traditional high-cost Czochralski (CZ) and float-zone (FZ) materials. This study evaluates the application of an advanced solar cell process that features a novel method of ion-implantation and backside rounding process on p-type quasi-mono silicon wafer. The ion implantation process substituted for thermal POCl3 diffusion leads to better R sheet uniformity (

A Ni(II)-mixed-chalcogenolate carbonyl complex, [PPN][Ni(CO)(SePh)2(S-p-C6H4-Cl)] (1) was obtained from the treatment of [CpNi(μ-S-p-C6H4-Cl)]2 and fac-[PPN][Fe(CO)3(SePh)3]. Using 1 as a precursor, two four-coordinated square planar Ni(II)-chalcogenolate/chalcogenol complexes, [PPN][Ni-(SePh)(N(CH2CH2S)2(CH2CH2SH))] (2) and [Ni(PEt3)(N(CH2CH2S)2(CH2CH2SH))] (4) containing the thiol in the secondary coordination sphere have been synthesized and identified by single-crystal X-ray diffraction. Analyses of structural data and vibrational energy (νSH = 2431 cm−1 for 4) reveal that the pendant thiol in complexes 2 and 4, respectively do not form intramolecular interaction with the nickel and thiolato sulfur. Compared to previously reported analogues coordinated by [P(o-C6H4S)2(o-C6H4SH)]2−ligand (Chen, C.-H.; Lee, G.-H.; Liaw, W.-F. Inorg. Chem. 2006, 45, 2307), the lack of intramolecular interaction in complexes 2 and 4 may be attributed to the rotatable C-S and C-C bonds of [N(CH2CH2S)2(CH2CH2SH)]2− ligand, precluding the pendant thiol from pointing a direction to the nickel and thiolato sulfur.

the H2O2 source. Few examples for the Mn II -mediated reduction of O2 yielding the Mn–O2 adduct were reported. [7–10] Hoffman and co-workers reported that Mn II TPP(py) can act as an oxygen carrier at low temperature to form a Mn(TPP)(O2) complex with a Mn IV (O2) 2� formalism and the binding mode of the peroxo ligand was suggested as symmetric side-on. [7] Another example reported by the Wieghardt group is the binuclear [L2Mn2(m-O)2(m-O2)] 2+ complex, which contains a peroxo bridge between two Mn IV ions. [9] Recently, Borovik and co-workers showed that reaction of [Mn II H2bupa] � and O2 at ambient temperature produces monomeric Mn III -peroxo complexes. [10] In this system, the noncovalent interactions (hydrogen bonding) within the secondary coordination sphere support the activation of O2. [11] In this report, we demonstrate that the complex [Mn I (CO)3(P(C6H3-3-SiMe3-2-S)2(C6H3-3-SiMe3-2-SH))] � , 1b , with the pendant thiol group in the secondary coordination sphere can activate molecular oxygen, leading to the formation of the monomeric, O2-side-on-bound Mn IV complex, [Mn(O2)(P(C6H3-3-SiMe3-2-S)3)] � , 3. Reaction of cis-[Mn(CO)4(SC6H5)2] � with one equivalent of P(C6H3-3-R-2-SH)3 (R = H or SiMe3) in tetrahydrofuran (THF) solution at 508C, respectively, produced the sixcoordinate [Mn(CO)3(P(C6H3-3-R-2-S)2(C6H3-3-R-2-SH))] � (R = H, 1a ; SiMe3, 1b ) isolated as a yellow solid in high yield (95 % for 1a ; 92 % for 1b ). The IR spectra of 1a and 1b show the same CO stretching bands at 1989(vs), 1908(s), and 1886(s) (Figure 1), consistent with a tricarbonyl derivative possessing pseudo C3v symmetry. [12] Complex 1a can be crystallized by vapor diffusion of diethyl ether into a concentrated THF/CH3CN (3:1, v/v) solution at � 208C in nitrogen. [13] Figure 1 displays a thermal ellipsoid plot of 1a .T he manganese center is coordinated by one phosphorus, two thiolate sulfur atoms, and three CO groups in a facial position, in agreement with the infrared data. The structural data also reveal that 1a contains a pendant thiol group in the secondary

Fine spherical mesocarbon-microbeads (MCMBs), having average particle sizes of 24.57, 11.69 and 10.74 μm, were mixed with various amounts of solid-resins (with high β-resin contents) to prepare graphite-matrixes in self-sintering reactions. The results indicate that the self-sintering reactions of the MCMBs can be significantly improved by enhancing the contacting-pattern of the mixture. MCMBs with smaller particle sizes favor self-sintering reactions and can be used to form high-quality graphite-matrixes. In addition, the self-sintering reactions are strongly dependent on the β-resin content of the raw materials. The bending strength of the graphite-matrixes increases, while the density of the graphite-matrixes decreases, with an increase of the β-resin content in the raw materials. The optimum β-resin content in the mixtures needed to obtain high density graphite-matrixes is approximately 5.0 wt.%.

Background and Purpose The safety and efficacy of treating serious infections caused by Staphylococcus aureus with daptomycin in a Taiwanese population were studied. Methods A retrospective, multicenter study was performed in Taiwan between December 2007 and June 2009. This study included adult hospitalized patients who had received intravenous daptomycin therapy for infections caused by S aureus . All patients were followed until discharge from the hospital or death. Results A total of 52 patients (males, n =44; median age: 62 years) were evaluated. Infections included complicated skin and soft-tissue infections ( n =14), catheter-related bacteremia ( n =14), osteomyelitis and septic arthritis ( n =12), endovascular infections and endocarditis ( n =11), and urinary tract infections ( n =1). Overall, 47 (90.4%) patients were successfully treated and their clinical symptoms were resolved. Adverse effects related to daptomycin were detected in nine patients, but none were required to discontinue daptomycin. Conclusion The results support daptomycin as an effective and safe treatment for staphylococcal infections in Taiwanese populations.

A microstrip antenna design that effectively attains circular polarization (CP) and harmonic suppression is proposed. By modifying the size and position of two peripheral cuts, two orthogonal modes that have equal amplitude and are 90 out of phase are simultaneously excited. The four right-angle slits embedded in the antenna can block the second- and third-order harmonic signals. This property is especially suitable for nonlinear circuit applications, such as active integrated antenna (AIA) and rectifying antenna (rectenna). The adopted CP antenna built on a low-cost FR4 substrate has a measured bandwidth of 137 MHz (10-dB return loss) and a 30-MHz CP bandwidth (3-dB axial ratio). A rectenna that comprises the proposed antenna and a rectifying circuit is built for verifying the characteristics of the proposed antenna. The measured results of the proposed antenna are in good performances and steady efficiency.

A novel antenna design that effectively covers three bands (the medical implant communications service (MICS) band at 402 MHz, and the industrial, scientific, and medical (ISM) band at 433 MHz and 2.45 GHz) using a π-shaped radiator with a stacked and spiral structure is described. The antenna has compact size of 254 mm 3 (10 mm by 10 mm by 2.54 mm). The proposed design is effective for triple-band biotelemetry with data telemetry (402 MHz), wireless powering transmission (433 MHz), and wake-up controller (2.45 GHz). An experimental prototype of the compact stacked rectenna was fabricated on a Roger 3210 substrate. This antenna was used in a rectenna (rectifying antenna) for 433 MHz wireless powering transmission, and provided a conversion efficiency of 86% when 11 dBm microwave power was received at 433 MHz with a 5 kΩ load. The optimal antenna was fabricated and tested in a minced front leg of pork. The simulated and measured bandwidths were 86 MHz and 113 MHz in the MICS band, and 60 MHz and 70 MHz in the ISM band, respectively.

This letter presents an on-chip millimeter-wave (MMW) Yagi-Uda antenna implemented by the integrated passive device (IPD) process. This antenna consists of a half-wavelength dipole element and two director elements to achieve higher directivity than conventional wire dipole antennas and is excited using a micro-strip via-hole balun structure. Measurements indicate that the on-chip antenna achieves the bandwidth of 18% (53.8-64.8 GHz), a peak gain of 6 dBi. The simulated front-to-back ratio and radiation efficiency are 15 dB and 93%, respectively. Compared to the CMOS process, the characteristics of the designed antenna are much better. Thus, this 60-GHz chip antenna obtains a compact size of 1.5 × 1.8 mm2, high efficiency, and high-gain advantages.

In this paper, analyses on sensitivity and link budget have been presented to guide the design of high-sensitivity noncontact vital sign detector. Important design issues such as flicker noise, baseband bandwidth, and gain budget have been discussed with practical considerations of analog-to-digital interface and signal processing methods in noncontact vital sign detection. Based on the analyses, a direct-conversion 5.8-GHz radar sensor chip with 1-GHz bandwidth was designed and fabricated. This radar sensor chip is software configurable to set the operation point and detection range for optimal performance. It integrates all the analog functions on-chip so that the output can be directly sampled for digital signal processing. Measurement results show that the fabricated chip has a sensitivity of better than -101 dBm for ideal detection in the absence of random body movement. Experiments have been performed successfully in laboratory environment to detect the vital signs of human subjects.

This work presents a novel broadband monopole antenna for digital video broadcasting-terrestrial (DVB-T) application. The proposed antenna consists of a multiple-ring radiating patch and a sleeve-shaped ground plane. The multiple-ring monopole is used to realize the antenna height reduction at a flxed operating frequency. It shows a wide operating 2.5:1 VSWR bandwidth of 408MHz achieved by using an impedance-matching technique. The technique applies cutting a notch at the ground plane opposite to the microstrip line and adjusting the height of the sleeve-shaped ground. The proposed antenna can operate in the 463{871MHz frequency range and cover the DVB-T operating bandwidth (470{862MHz). The radiation pattern of the proposed antenna in the xy-plane is omni-directional with a peak antenna gain of 4.2dBi.

A compact planar inverted-F antenna (PIFA) consisted of two meandered strips with bandwidth enhancement technique is proposed for implantable biotelemetry in MICS band. The antenna occupies a volume of only 791 mm3 (22.5 mm by 18.5 mm by 1.9 mm) operating at 402 MHz. PIFA with two meandered strips can excite dual-resonate frequencies that control the resonant frequencies at 380 and 440 MHz, respectively, to obtain the broad bandwidth of 120 MHz (353–473 MHz) at a return loss of 10 dB. To verify the performance of implantable antenna, the test tissue is adopted as implanting environment by grinding the pork of front-leg. Furthermore, the property of this antenna can remain consistency against the varying and complex human tissue. Thus, this letter provides a miniature, broadband implantable PIFA for biotelemetry of medical devices. © 2009 Wiley Periodicals, Inc.

A novel rectifying antenna (rectenna) using a compact circularly polarized (CP) patch antenna with RF-to-DC power conversion part at 2.45 GHz is introduced, in which the unbalanced slots structure is adopted for size reduction and 2nd harmonic rejection. To contribute a rectenna for RF power conversion, the back side of the CP antenna is the doubler rectifier circuit with 3rd order harmonic rejection radial stub for efficiency optimization and harmonic power re-radiation elimination. The adopted CP antenna built on low cost FR-4 substrate has measured bandwidth of 137 MHz (10 dB return loss) as well as 30 MHz CP bandwidth (3 dB axial ratio). By up to 3rd order harmonic rejection, the RF-to-DC conversion efficiency would reach 53% and 75% with 1 K Omega resistor load under ANSI/IEEE uncontrolled and controlled RF human exposure limit respectively.

Compared to [Ni(II)(SePh)(P(o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-SH))]- (1a) and [Ni(II)(Cl)(P(o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-SH))]- (3a) with a combination of the intramolecular [Ni...H-S] and [Ni-S...H-S] interactions, complexes [NiII(SePh)(P(o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-SH))]- (1b) and [Ni(II)(Cl)(P (o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-SH))]- (3b) with intramolecular [Ni...H-S] interaction exhibit lower nu(S-H) stretching frequencies (2137 and 2235 cm(-1) for 1b and 3b vs 2250 and 2287 cm(-1) for 1a and 3a, respectively) and smaller torsion angles (27.2 degrees for 3b vs 58.9 and 59.1 degrees for 1a and 3a, respectively). The pendant thiol interaction modes of 1a, 3a, and 3b in the solid state are controlled by the solvent pairs of crystallization. Oxygen oxidation of dinuclear [Ni(II)(P(o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-SH))](2) (4) yielded thermally stable dinuclear [Ni(III)(P(o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-mu-S))](2) (5). The two paramagnetic d(7) Ni(III) cores (S = 1/2) with antiferromagnetic coupling (J = -3.13 cm(-1)) rationalize the diamagnetic property of 5. The fully delocalized mixed-valence [Ni(II)-Ni(III)] complexes [Ni2(P(o-C(6)H(3)-3-SiMe(3)-2-S)(3))(2)]- (6) and [Ni(2)(P(o-C(6)H(3)-3-SiMe(3)-2-S)(3))(P(o-C(6)H(3)-3-SiMe(3)-2-S)(2)(o-C(6)H(3)-3-SiMe(3)-2-SCH(3)))] (7) were isolated upon the reduction of 5 and the methylation of 6, respectively. The electronic perturbation from the sulfur methylation of 6 triggers the stronger Ni...Ni interaction and the geometrical rearrangement from the diamond shape of the [NiS(2)Ni] core to the butterfly structure of [Ni(mu-S)(2)Ni] to yield 7 with Ni...Ni distances of 2.6088(1) A. The distinctly different Ni...Ni distances (2.6026(7) for 5 and 2.8289(15) A for 6) and the coordination number of the nickels indicate a balance of geometrical requirements for different oxidation levels of [PS(3)Ni-NiPS(3)] cores of 5 and 6.
