The tetranucleating manganese(III) and copper(II) complexes of the type Mn4LP2, Cu4LP2, where H6LP2 = 1,4 bis[2′- hydroxy-3′-(iminotetraphenylporphyrin)-5′-methylbenzyl] piperazine, were synthesized and characterized. Mn4LP2 complex is EPR silent and this indicates that manganese is in +3 oxidation state. Cu4LP2 complex showS broad band with g value centered at 2.06 indicates antiferromagnetic coupling. Cyclic voltammetry studies indicating that the Mn4LP2 complex undergoes quasireversible electron transfer in the cathodic potential region and irreversible electron transfer in the anodic potential region. Cu4LP2 complex undergoes irreversible electron transfer in the cathodic potential region, quasireversible electron transfer in the anodic potential region.
