Binuclear antiferromagnetically-coupled hydroxo-bridged copper(II) complexes with positive reduction potentials and involving sequential two electron transfer at the same potential

Abstract

Binuclear hydroxo-bridged copper(II) complexes of some tetradentate phthalazine and pyridazine ligands represent the first examples of binuclear copper(II) complexes exhibiting sequential two electron reduction at positive potentials (0.40 to 0.45 V vs. standard calomel electrode), comparable to those observed for Type III copper protein centres.
