Two novel vic-dioxime, 1,2-dihydroxyimino-1-p-tolyl-3-aza-6-imidazole heptane (L1H2) and N-(ethyl-4-amino-1-piperidine carboxylate)-p-tolylglyoxime (L2H2) were prepared by the reaction of anti-p-tolylchloroglyoxime with 1-(3-aminopropyl)imidazole and ethyl-4-amino-1-piperidine carboxylate in absolute THF. Mononuclear complexes with a metal-ligand ratio of 1:2 were prepared using Co(II), Cu(II) and Ni(II) salts. The ligands and their Co(II), Cu(II) and Ni(II) com plexes were characterized by elemental analyses, FT-IR, UV-Vis, 1H-NMR and 13C-NMR and magnetic susceptibility measurements. The electrochemical behaviour of the complexes was investi ated by cyclic voltammetry in dimethylsulfoxide. All metal complexes showed metal centered quasi reversible one-electron redox processes. How ever, metal complexes of the L2H2 ligand also ex hibited ligand based irreversible redox waves.
