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 degrees C. Reaction of two vic-dioxime ligands with MCl2 center dot nH(2)O (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)center dot 2H(2)O]. All of metal complexes are non-electrolytes as shown by their molar conductivities (Lambda(m)) 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, H-1 NMR and C-13 NMR, magnetic susceptibility measurements, molar conductivity measurements. Furthermore, redox properties of the metal complexes were investigated by cyclic voltammetry.
