In the present paper three new heterotrimetallic Cu(II)-Zn(II)-Cu(II) complexes have been synthesized and characterized by analytical and spectroscopic studies. The molar conductance values for the complexes fall in the region 1.2-1.7Ω(-1)cm(2)mol(-1) in DMSO solution indicating that all of the complexes are non-electrolyte. The dihydrazone ligand is present in enol form in all of the complexes. Both the copper centres have distorted square pyramidal stereochemistry in all of the complexes while the zinc centre in all hetero metal complexes has octahedral stereochemistry. The EPR parameters of the complexes indicate that the copper centre has [Formula: see text] orbital as the ground state. The electron transfer reactions of the complexes have been investigated by cyclic voltammetry.
