The crystal structures of 2 and 3 complexes have been determined by single crystal X-ray diffraction. Both copper(II) and nickel(II) ions adopt a distorted square planar geometry in [Cu(Me-salabza)] and [Ni(salabza)] complexes. The cyclic voltammetric studies of these complexes in dichloromethane indicate the electronic effects of the methyl groups on redox potential.Unsymmetrical N2O2 Schiff baseNi(II) and Cu(II) complexesCrystal structureCyclic voltammetrytext::journal::journal article::research article
