The water splitting reaction represents an appealing approach to store solar energy. 4e−/4H+ oxidation of generating O2 is considered as the bottleneck in this and usually requires a rather large over potential. We report on synthesis application binuclear cobalt(III) complex, 1, with two μ-OH ligands tripodal triazole ligands, L, electrochemical (WOR; L=tris((1-phenyl-1H-1,2,3-triazol-4-yl)met...

The self-assembly of higher order structures in water is realised by using the association of 1,3-biscarboxylates to binuclear meta-xylyl bridged DO3A complexes. Two dinicotinate binding sites are placed at a right-angle in a rhenium complex, which is shown to form a 1 : 2 complex with α,α'-bis(Eu·DO3A)-5-amino-m-xylene.

A series of complexes of europium (III)/gadolinium (III) with 2-thienyltrifluoroacetonate (HTTA), terephthalic acid (TPA) and phenanthroline (Phen) were synthesized by coprecipitation. The resulting complexes including Eu2(TPA)(TTA)4Phen2, Eu1.4Gd0.6(TPA)(TTA)4Phen2, Eu1.0Gd1.0(TPA)(TTA)4Phen2 and Eu0.8Gd1.2(TPA)(TTA)4Phen2 were characterized by elemental analysis, IR spectroscopy and thermal s...

In the complex cation of the binuclear solvated title salt, [Pt2F(SbF6)2(C8H12)2]SbF6 0.75HF, an F atom bridges the two platinum(II) atoms with a bond angle of 123.3 (2) . The corresponding Pt—F bond lengths are in the range of other fluorine-bridged binuclear platinum(II) complexes. Two of the three SbF6 anions each coordinate with one F atom to one platinum(II) atom. Including the -bound cycl...

In the title centrosymmetric binuclear Cu(II) complex, [Cu2(C7H4ClO2)4(C10H14N2O)2], the two Cu(II) cations [Cu⋯Cu = 2.6314 (4) Å] are bridged by four 3-chloro-benzoate (CB) anions. The four carboxyl-ate O atoms around each Cu(II) cation form a distorted square-planar arrangement, the distorted square-pyramidal coordination geometry being completed by the pyridine N atom of the N,N-di-ethyl-nic...

It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N',N''-donating imine ligand led to a mononuclear compound, namely di-chlorido-[N,N-dimethyl-N'-(pyridin-2-yl-methyl-idene)ethane-1,2-di-amine]copper(II) monohydrate, [CuCl2(C10H15N3)]·H2O, 1, while the N,N',O-donating imine ligand produc...

Binuclear Cu proteins play vital roles in O(2) binding and activation in biology and can be classified into coupled and noncoupled binuclear sites based on the magnetic interaction between the two Cu centers. Coupled binuclear Cu proteins include hemocyanin, tyrosinase, and catechol oxidase. These proteins have two Cu centers strongly magnetically coupled through direct bridging ligands that pr...

A series of cationic binuclear (η(6)-cymene-Ru)2 complexes with N2S2-ligands were synthesized in 64% to 85% yield by reaction of [Ru(η(6)-cymene)Cl2]2 with bis-S,S'-(ortho-aminothiophenol)-xylenes as BF4(-) and PF6(-) salts. The compounds were studied using NMR, HRMS, UV-vis and IR spectroscopy, EA and inductively coupled plasma (ICP) MS. It was determined that the hinged binuclear Ru complexes...
