Mononuclear nickel(II), copper(II), and cobalt(II) complexes have a metal-ligand ratio of 1:2 in which the ligands coordinate through the two nitrogen atoms as do most vic-dioximes. The ligands and their Co(II), Cu(II), and Ni(II) complexes were characterized by elemental analyses, FT-IR, UV-vis, 1H-NMR and 13C-NMR, magnetic susceptibility measurements, electrical conductivity measurements and cyclic voltammetry. The electrical conductivity of Ni(II), Co(II), and Cu(II) metal complexes were measured using Four-Point Probe analysis. The electrochemical behavior of the Ni(II), Co(II), and Cu(II) complexes were investigated by cyclic voltammetry in DMSO.eninfo:eu-repo/semantics/closedAccessMetal ComplexesMolar ConductivityRedox PropertiesSynthesisVic-DioximeCoordination chemistry of nickel(II), copper(II), and cobalt(II) with MN4 core-containing two novel vic-dioximes ligands.
