Abstract
Two 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(L xH)2·H2O]. 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.
