Summary
The complex bis[2-(2-pyridyl)benzimidazole]copper(I) perchlorate, [Cu(PBIM)2]ClO4, has been prepared and its oxidation with molecular oxygen in acetonitrile studied. Dependence of the rate constant, k0, upon an excess of ligand was not observed. The rate constant for the oxidation of this complex was found to be 30 M−2s−1. The corresponding copper(II) compound behaves as a 1∶1 electrolyte, commensurate with one of the complexed ligands losing a hydrogen.
