The Synthesis and Characterization of Some Metal Complexes Derived From 1,3-Dioxalane Groups and Vic-Dioxime Ligands

Abstract

A novel substituted vic-dioxime ligand containing the amino group, N,N′-[3,3′-{ethane-1,2-di-yl-bis(oxy)bis(3,1-phenylene)} bis(N′-hydroxy)-2-(hydroxyimino)acetimid amide], L1, has been prepared from 1,2-bis(m-aminophenoxy)ethane, antichloroglyoxime. This vic-dioxime ligand with Cu(II), Ni(II), Co(II) and Cd(II) complexes of 6,7-O-Cyclopentlydine-1-amino-4-azaheptane, L2, have been reacted at 60-65 °C temperature. The ligand1 :metal:ligand2 ratio of these complexes have been found to be 1:2:2. The Cu(II), Ni(II), Co(II) and Cd(II) complexes of these ligands are proposed to be octahedral. The vic-dioxime (L1)
with some transition metal complexes of amine (L2) have been characterized by elemental analyses, molar conductivity, magnetic susceptibility, IR, 1 H-NMR, UV-Vis spectra and TGA techniques
