An autocatalytic photoinitiated reaction helps decomposition of the alizarin-based ruthenium(ii) bipyridine complex in presence hydrogen peroxide.

The electrochemical reduction of allyl chloride is strongly catalyzed in the presence of cobalt complexes of 2,2'-bipyridine. A prominent reaction product of the catalyzed reduction is 1,5-hexadiene. Voltammetry, coulometry, and gas chromatographic data are presented and analyzed and a mechanistic scheme proposed to. account for the catalytic action of the cobalt-2,2'-bipyridine complexes. Rece...

The reactions of nickel(0) complexes with phosphine, bipyridine-type, and N-heterocyclic carbene ligands aryl, vinyl, alkyl halides is reviewed.

Four iridium(III) dyes functionalized with aldehyde functional group in the cyclometalating (C^N) ligands, bearing either diethyl [2,2′-bipyridine]-4,4′-dicarboxylate or tetraethyl [2,2′-bipyridine]-4,4′-diylbis(phosphonate) anchoring groups, coded as Ir1–Ir4, are synthesized and explored photosensitizers. The synthetic route is described all of complexes characterized respect to their electroc...

The synthesis and characterization of eight new bis-cyclometalated compounds [M(ptpy)2(N^N)]PF6 (ptpy=2-(p-tolyl)pyridinato; N^N=5-chloro-1,10-phenanthroline: M=Rh, 1; M=Ir, 2); N^N=5-methyl-1,10-phenanthroline: 3; 4; N^N=4,4’-diphenyl-2,2’-bipyridine: 5; 6; N^N=4,4’-diamino-2,2’-bipyridine: 7; 8) are described. All were characterized by spectroscopic means. Additionally, the molecular structur...

Z. Naturforsch. 2011, 66b, 894 – 898; received June 19, 2011 Assembly reaction of copper(I) chloride, 2,2′-bipyridine-3,3′-dicarboxylic acid (H2L) and 2,2′-bipyridine results in the formation of a new complex [Cu2(C12H6O4N2)2(2,2′-bipy)2] ·CH3OH (1). In 1, two L2− ligands link two Cu(II) ions to form a dinuclear structure. The electrochemical and magnetic properties of 1 were investigated. The ...

The first metal complexes of 2,5-di(2-pyridyl)thiazolo[5,4-d]thiazole (5) are described. X-Ray crystal structures are reported for the free ligand 5, a dinuclear copper complex 6 and the two diastereoisomers, 7meso and 7rac, of the dinuclear bis(2,2'-bipyridine)ruthenium complex. The two diastereoisomers of 7 and the 4,4'-dimethyl-2,2'-bipyridine analogue 8 are readily separated by cation excha...

In the title hydrated coordination polymer, {[Zn(C6H2O5)(C10H8N2)(H2O)]·2H2O} n , an infinite [1-10] chain is formed by the linking of [Zn(C10H8N2)(H2O)](2+) entities by bridging, monodentate furan-2,5-dicarboxyl-ate dianionic linkers. The Zn(2+) coordination geometry is a trigonal bipyramid, with one N atom (from 2,2'-bipyridine) and one O atom (from the bridging dianion) in the axial position...

In the title compound, [Co(C(7)H(3)Cl(2)O(2))(2)(C(10)H(8)N(2))(CH(3)OH)(2)](n), the Co(II) ion lies on a twofold rotation axis and is in a slightly distorted octa-hedral CdO(4)N(2) environment, formed by two O atoms from monodentate dichloro-benzoate ligands, two O atoms from methanol ligands, and two N atoms from trans-related 4,4'-bipyridine ligands. The bipyridine ligands also lies on a two...

A dinuclear ruthenium(II) complex linked via a reducible azo group [Ru(bpy)2(azobpy)Ru(bpy)2]Cl4 (Ru2azo, bpy=2,2'-bipyridine, azobpy=4,4″-azobis (2,2'-bipyridine)) was adopted as a probe for thiols. Results showed that Ru2azo could selectively and effectively react with biological thiols (such as cysteine, homocysteine and glutathione) with a 10(-7)M detection limit. After it reacted with thio...
