Binuclear copper complexes with (CuCuI)-Cu-I and Cu+1.5Cu+1.5 core structures formed in the reactions of 3-(2-methylbutyl)-5-pyridylmethylene-2-thiohydantoin with copper(II) acetylacetonate and copper(II) chloride

摘要

A treatment of the ligands, 3-(2-methylbutyl)-5-pyridylmethylene-substituted 2-thio-3,5-dihydro-4H-imidazole-4-one (L) with CuCl2 center dot 2H(2)O in MeOH/CH2Cl2 or Cu(acac)(2) in MeOH/CH2Cl2 affords to binuclear complexes with the [L-H](2)Cu+1.5Cu+1.5Cl or [L-H](2)(CuCuI)-Cu-I composition, respectively. X-ray crystallography demonstrated close Cu-Cu interaction for the first complex and the absence of Cu-Cu bonding for the second one.
