A dinuclear cobalt complex with a doubly N-confused hexaphyrin, Co2DNCH, showed high catalytic activity for electrochemical hydrogen reduction due to the wide π-conjugated system of DNCH.

Di- or tetracarboxylic acid ligands were used to isolate molecular coordination complexes containing the association of several mononuclear {Nb 1 } moiety and dinuclear 2 O} niobium( v ) polyoxo clusters.

For the first time, functionalized mesoporous silica nanoparticles (MSNs) with dinuclear Schiff-base complexes were synthesized as attractive organic–inorganic hybrids and their capability investigated for loading antibiotic drugs immobilization of enzymes.

A series of dinuclear [Ni(II)Ln(III)] Schiff-base complexes (using a Schiff-base dicompartmental ligand derived from o-vanillin [H(2)valpn = 1,3-propanediylbis(2-iminomethylene-6-methoxy-phenol)]) with Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, and a hydroxo-bridged tetranuclear [Ni(II)Yb(III)] are reported. The crystal structures have been solved for 10 dinuclear complexes revealing four...

The incorporation of benzene-l,2-dithiolato building blocks into supramolecular coordination assemblies is the main objective of the investigations described here. Special interest is directed towards dinuclear complexes with bis(benzene-l,2-dithiolato) ligands, which might be able to form helical structures. Bis(benzene-l,2-dithiolato) ligands are accessible by ortho-functionalization and subs...

We demonstrate that the insertion of dinuclear active site [FeFe] hydrogenase into apo-enzyme can occur when enzyme is embedded in a film redox polymer, under conditions mediated electron transfer.

Dinuclear iron peroxido complexes are important intermediates for selective oxidation reactions. A detailed kinetic study of the reaction benzoyl chloride (BzCl) with a dinuclear non-heme cis end-on complex ligand EtHPTB (N,N,N′,N′-tetrakis[(N-ethyl-2-benzimidazolyl)methyl]-2-hydroxy-1,3-diamino-propane) had been performed. The starting complex, can be obtained either by iron(II) O2 or instead,...

The design of dissymmetric organic ligands has been exploited to produce heterometallic dinuclear and trinuclear lanthanide-based coordination compounds with the requirements act as logical quantum gates for spin-based computing.

Macrocyclic heterobinuclear Zn(II)–Cu(II) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. The ligands include similar N4O2 and dissimilar N(imine)3O2 and N(amine)3O2 coordination sites sharing two phenolic oxygen atoms. The six-coordination site comprises two pyridyl pendant arms on the amine nit...

In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...
