A porphyrin-based cubic cage (Cube) was reacted with a Pt(II)-based molecular H2-evolving catalyst, PtCl2(dmbpy) (PtDmb; dmbpy: 4,4′-dimethyl-2,2′-bipyridine), to give Cubes incorporated with one o...

Monodispersed tetrapod-shaped ZnO (T-ZnO) particles with rods ranging from 1.3 to 10.5 µm are synthesized by gas-phase reaction of zinc vapor and oxygen gas using a flow restrictor in a single baki...

An ITO (indium tin oxide) electrode modified with [Ru(terpy){4,4′-(CH2PO3H2)2-2,2′-bpy}(OH2)]2+ was prepared to gain insight into the mechanism of O2 evolution from water catalyzed by a series of m...

Photoirradiation on [Pd02(dppm)3] (dppm = bis(diphenylphosphino)methane) in 1,2-dichloroethane solution with visible light yields [PdI2Cl2(dppm)2] (2) and ethylene quantitatively. Irradiation of 2 in various solutions shows interesting photochromic behavior.

An X-ray crystal structure determination has been carried out on a free macrobicyclic ligand pytren (1,4,12,15,18,26,31,39,42,43,44,-undeca-azapentacyclo-[13.13.13.16,10.120,24.133,37]-tetratetraconta-4,6(42),7,9,11,18,20(43),21,23,25,31,33(44),34,36,38-pentadecane). It shows a different conformation from its Ba complex for direction of lone pairs of the six imine nitrogen atoms. Addition of dimethylsulfoxide (DMSO) to the acetonitrile solution of the Ba complex causes the conformational change of pytren ligand and driving out of the Ba ion from the cavity due to interactions of the complex with DMSO.

New mononuclear metal-cage complexes of a macrobicyclic ligand, pytren (metal = Ba(II), K(I), and Cs(I) and pytren = 1,4,12,15,18,26,31,39,42,43,44-undeca-azapentacyclo[13.13.13.16,10.120,24.133,37]tetratetraconta-4,6(42),7,9,11,18,20(43),21,23,25,31,33(44),34,36,38-pentadecaene), were prepared and characterized including the crystal structure analysis of [Ba(pytren)](B(C6H5)4)2.

[Ru(tmtacn)(R2bpy)(OH2)]2+ (tmtacn = 1,4,7-trimethyl-1,4,7-triazacyclononane; R2bpy = 4,4′-disubstituted-2,2′-bipyridines, R=H, Me, and OMe) with tmtacn ligated in a facial fashion is found to be a...

An air-stable dinuclear iron–dithiolene complex with an Fe2(μ-S)2 core, [FeIII(mnt)2]22− (mnt = maleonitriledithiolate), has been found to serve as an electrode catalyst toward the reduction of wat...

Experiments show that [Ru(terpy)(bpy)(OH2)]2+ is highly active as a catalyst toward oxidation of water into molecular oxygen in spite of the mononuclear character of the complex, while [Ru(terpy)(b...

The second example of a photo-hydrogen-evolving (PHE) molecular device consisting of a Ru(bpy) 3 2+ (bpy = 2,2'-bipyridine) derivative and a cis-PtCl 2 unit has been successfully prepared and characterized to reveal that the PHE activity is quite sensitive to the structural modification at the bridging spacer unit connecting the Ru II and Pt II centers.

Chiral Mn(salen) complex 3 bearing a 1-ethyl-1-methylpropyl group at C3, C3′, C5, and C5′ was found to induce higher asymmetry in the epoxidation of conjugated Z-olefins, especially less nucleophil...

Photo-irradiation upon the chlorobenzene solution of [Pd(PPh3)4] affords trans-[PdCl2(PPh3)2] and a mixture of chlorobiphenyls. In the presence of zinc and organic amines, the catalytic production of chlorobiphenyls mediated by the palladium complex was observed with irradiation of light.

A new triple-decker type rubidium(I) complex containing 18-membered macrocyclic ligands has been synthesized and characterized by X-ray crystallography. Linear stacks of the triple-decker units have been revealed in the crystal.

Structural studies by X-ray analysis and NMR spectroscopy of the π-allyl complex, [Pd(η3-1,3-diphenylallyl)((S)-BINAP)]PF6·AcOEt, have been carried out, and revealed the stereochemical feature for the intermediate of palladium-catalyzed asymmetric allylic alkylation. The dissimilarity of the two phenyl groups attached to the π-allyl moiety is assumed to be one of the origin of the selectivity. In solution two configurational isomers, (syn, syn) and (syn, anti), exist.
