Synthesis, crystal structure, magnetic and spectroscopic properties of {[Cu(oxbe)(py)]2Ni(py)2}·2Dmf complex of dissymmetrical oxamidate

Abstract

The trinuclear complex {[Cu(oxbe)(py)]2Ni(py)2}·2DMF has been prepared and characterized by elemental analysis, IR and electronic spectra and magnetic susceptibility, where H3oxbe is the dissymmetrical ligand N-benzoato-N′-(2-aminoethyl) oxamido, py = pyridine, DMF = dimethylformamide. The molecular structure of this complex is centrosymmetrical and has an extended oxamido-bridged structure consisting of two pyramidal copper(II) and one octahedral nickel(II) ions. The central Ni(II) and two terminal Cu(II) ions are antiferromagnetically coupled, J = − 60.2 cm−1.
