Abstract

A series of heterodinuclear complexes, [MZnL][ClO4)2· nH2O (M = Cu, Ni, and VO) where L is a dinucleating Schiff base ligand derived from the condensation of 2,6-diacetyl-4-methylphenol (1mole), with ethylenediamine (1mole), 1,2-diaminopropane (1mole), or 1,3-diaminopropane (1mole) have been synthesized and evaluated. The complexes exhibit a single one-electron redox couple as anticipated. The e.s.r spectra for the CuZn complex shows an isotropic signal and the frozen glass spectra of VOZn complex is characterized by two sets of eight lines.
