Özet

A new vicinal dioxime ligand with two 2-benzimidazolylmethyl groups, namely S,S'-bis(2-benzimidazolylmethyl)dithioglyoxime (H2L), has been prepared from cyanogen-di-N-oxide and 2-mercaptomethylbenzimidazole in dichloromethane at -10-degrees-C. Nickel(II), palladium(II), cobalt(II) and cobalt(III) complexes of H2L have a metal : ligand ratio of 1 : 2 and the ligand coordinates through the two N atoms, as most of the vicinal dioximes. [Co(HL)2(L')Cl] has been prepared with L'= pyridine, 2,6-dimethylpyridine, 2-mercaptopyridine, 2-carboxypyridine, pyridine-2-carboxyaldehyde, triphenylphosphine, triphenylarsine, together with a chloride ion as axial ligands. All these complexes are slightly soluble in common organic solvents. Structures are proposed according to elemental analyses, H-1, C-13-NMR, IR, and UV-Visible spectral data.
