A novel Schiff base obtained by the reaction of 1,3-bis-(oaminophenoxy)propane and 2-hydroxynaphthalin-1-carbaldehyde, forms complexes with Co(II), Cu(II) and Ni(II). The Schiff base ligand and its metal complexes have been characterized by elemental analysis, microanalytical data, magnetic measurements, UV-visible, H-1 NMR, C-13 NMR and IR-spectra as well as conductance measurements. Electrochemical data show that NiL and CuL complexes undergo metal based quasi-reversible one-electron redox processes. However, metal complexes also exhibit ligand based irreversible redox waves. The electrochemical results also indicate that the electron transfer rate is higher for NiL complex than the CuL complex. Voltammetric data reveal easier electron donor properties for the NiL complex.
