Abstract

Coexistence of humans and large carnivores is a major challenge for conservation and management, especially in human‐modified landscapes. Ongoing recovery of some large carnivore populations is good conservation news, but it also brings about increased levels of conflict with humans. Compensation payments and preventive measures are used worldwide as part of conservation programmes with the aim of reducing such conflicts and improving public attitude towards large carnivores. However, understanding the drivers triggering conflicts is a conservation priority, which helps prevent and reduce damages. Here, we have analysed the spatio‐temporal patterns of brown bear Ursus arctos damages to apiaries, crops and livestock in the two small, isolated and endangered bear populations in northern Spain. The increase in the number of damages varied in parallel with the increase in bear numbers, which is probably a primary cause determining the occurrence on damages. Damages also varied among years, seasons and bear populations and seemed to mainly depend on the local availability of natural food items, weather conditions and the availability of apiaries and livestock. Fluctuating availability of food items may explain the frequency of conflicts, which is yet another call to apply preventive measures in carnivore damage to human property in seasons and years when natural food availability is lower than usual. Understanding and preventing damage is in turn essential to mitigate conflicts where humans and large carnivores share the same landscape. [ABSTRACT FROM AUTHOR]

Abstract

The reaction between bismuthate oxide and phen (1,10-phenanthroline) in acid medium led to the isolation of the unusual [(PhenH)(PhenH2)][BiCl6] 2H2O derivative, which has been characterized by X-ray analysis and IR spectroscopy. The compound crystallizes in the triclinic space group P1 with a = 8.313(2), b = 9.349(2), c = 9.807(3) A, a = 86.39(3), B = 110.27(3) and y = 106.48(3)°. The crystal structure is made of [BiCl6] 3- anions and [(PhenHXPhenr2)]3+cations. A network of hydrogen bond interactions involving the two clathrated water molecules, the phenanthroline moiety and the chlorines characterizes the entire structure.

32. Lanthanide(III) complexes of six-nitrogen-donor macrocyclic ligands with benzyl-type peripheral substituents, and crystal structure of [La(NO3)2(H2O)(C36H38N6)].(NO3)(H2O)

Abstract

Lanthanide(III) complexes of six-nitrogen-donor macrocyclic ligands carrying a benzyl-type group, -CH2-C6H4-X (X = -H, -OH, or -NH2), at each di-imine side-chain were synthesized by the Schiff-base condensation of 2,6-diacetylpyridine with substituted S- and R,S-1,2-diaminopropanes. The complexes were obtained as mixtures of constitutional isomers and stereoisomers, which were identified by 1H NMR spectra and separated by fractional crystallization. The molecular structure of the 11-coordinate complex [La(NO3)2(H2O)(C36H38N6)](NO3)(H2O) was established by X-ray crystallography.

Abstract

The reactions of cis-[PtCl2(NCMe)2] with a 5-fold excess of the primary aliphatic amines RNH2 (R = Me, Et, Pri, But) in CH2Cl2 at 10 °C afford in high yield the bis-amidine complexes cis-[PtCl2{Z-N(H)=C(NHR)Me} 2], where both the amidine ligands assume the Z configuration. The corresponding reactions of trans-[PtCl2(NCMe)2] with RNH2 (R = Me, Et, But) give a mixture of the bis-amidine trans-[PtCl2{Z-N(H)=C(NHR)Me}2] and the mono-amidine trans-[PtCl2(NCMe){Z-N(H)=C(NHR)Me}] derivatives, which could be isolated as pure products operating with a platinum nitrile complex:amine molar ratio of 1:50 or 1:1, respectively. The reaction of trans-[PtCl2(NCMe)2] with a 50-molar excess of PriNH2 affords the bis- amidine bis-amine dicationic complex trans-[Pt(H2NPri)2{Z-N(H)=C(NHPri)Me} 2]Cl2, which has been characterized also by X-ray diffraction analysis. The reactions of cis- and trans-[PtCl2(NCMe)2] with the secondary aliphatic amines R'R NH yield the bis-amidine complexes cis- and trans- [PtCl2{E-N(H)=C(NR'R)Me}2] (R', R = Et) and/or cis- and trans-[PtCl(NCMe) {E-N(H)=C(NR'R)Me}2] (R', R = Et; R' = Me, R = But), where the amidine ligands have the E configuration. The compound trans-[PtCl2(NCMe){E-N(H)=C (NMeBut)Me}] has been characterized by single crystal X-ray diffraction. All the complexes have been characterized by IR, 1H and 13C NMR spectroscopies. The Z or E configuration of the amidine ligand can be readily deduced by 1H NMR data.

Abstract

Cr[(eta5-C5H4CH2)2-2,6-C5H3N] (CrL) has been obtained by metathesis reaction between CrCl2 and Na2[(C5H4CH2)2-2,6-C5H3N] in THF at room temperature. Low-temperature H-1 NMR studies of CrL are reported. The solid state structure of CrL was determined by single crystal X-ray analysis (monoclinic, C2/c, a = 13.662(3) angstrom, b = 8.975(2) angstrom, c = 21.085(3) angstrom, beta = 95.11(4)-degrees, V = 2575.1(9) angstrom3, z = 8, R = 0.041, R(w) = 0.052 for 1619 measured reflections with I > 3sigma(I)). The ligand is bound to the metal atom via the two bent cyclopentadienyl rings with distances Cr-Cg(1) (Cg = gravity center) of 1.849(5) angstrom and Cr-Cg(2) of 1.840(5) angstrom, with the pyridine nitrogen at a distance Cr-N of 2.521(4) angstrom, which is the longest Cr-N value yet reported. The effects of the reduction in symmetry of this bent chromocene with respect to the unsubstituted one, which results in the perturbation of the axial ligand field typical of the undistorted metallocenes, are discussed in view of magnetic and optical investigations.
