Studies on Perchlorate Complexes of Cu(II) and Ag(I) with Substituted Benzimidazoles

Abstract

A series of perchlorate complexes of copper(II) and silver(II) of the compositions CuL₂(ClO₄)₂ L=2-(2´-quinolyl) benzimidazole (2-QylBzIH) 2,2´-bis(benzimidazyl) sulphide (bBzIH₂s), 2,2´-bis (benzimidazyl) ethane (bBzIH₂e) and AgLClO₄ (L=2,6-bis (2-benzimidazyl) pyridine (bBzIH₂Py), 2-QylBzIH, BbzIH₂s and BbzIH₂e have been prepared and characterised by conductivity, magnetic susceptibility, electronic, IR and proton NMR spectra. IR spectra give evidence for coordination of perchlorate in most of these complexes.
