Synthesis, Spectroscopic and Electrochemical Investigations of Two vic‐Dioximes and Their Mononuclear Ni(II), Cu(II) and Co(II) Metal Complexes Containing Morpholine Group

Abstract

AbstractTwo vic‐dioxime ligands (LxH2) containing morpholine group have been synthesized from 4‐[2‐(dimethylaminoethyl)] morpholine with anti‐phenylchloroglyoxime or anti‐monochloroglyoxime in absolute THF at −15 °C. Reaction of two vic‐dioxime ligands with MCl2·nH2O (M: Ni, Cu or Co and n = 2 or 6) salts in 1:2 molar ratio afforded metal complexes of type [M(LxH)2] or [M(LxH)2·2H2O]. All of metal complexes are non‐electrolytes as shown by their molar conductivities (Λm) in DMF (dimethyl formamide) at 10−3 mol·L−1. Structures of the ligands and metal complexes have been solved by elemental analyses, FT‐IR, UV‐Vis, 1H NMR and 13C NMR, magnetic susceptibility measurements, molar conductivity measurements. Furthermore, redox properties of the metal complexes were investigated by cyclic voltammetry.
