Mononuclear metal complexes with a metal-ligand ratio of 1:2 were prepared using Cu(II), Ni(II) and Co(II) salts. FT-IR spectra show that the ligands act in a tetradentate manner and coordinates N4 donor groups of ligands to Cu(II), Ni(II) and Co(II) ions. The Cu(II) complexes of these ligands are proposed to be square-planar; the Ni(II) and Co(II) complexes are proposed to be octahedral with two water molecules as axial ligands. The ligands and their metal complexes were characterized by elemental analyses, Ft-IR, UV-Vis, 1H and 13C-NMR spectra, magnetic susceptibility measurements and cyclic voltammetry. The electrochemical behavior of the Ni(II), Co(II) and Cu(II) complexes was investigated by cyclic voltammetry in DMSO as well.eninfo:eu-repo/semantics/closedAccesselectrochemical investigationsH-bondingmetal complexesoximesArticle397379387Q4WOS:000268875400004N/A2-s2.0-6954911511610.1080/15533170903129612
