FORMATION OF NOVEL AMINO VIC-DIOXIME COMPLEXES OF CU(II), NI(II), CO(II) AND CD(II) OF 1,3-DIOXALANE GROUPS CONTAINING THE OXIME MOIETY: THERMAL, MAGNETIC AND SPECTRAL STUDIES

Abstract

A novel substituted vic-dioxime ligand containing the amino group, N,N′-[2,2′-{ethane1,2-di-yl-bis(oxy)bis(2,1-phenylene)}bis(N′-hydroxy)-2-(hydroxyimino)acetimidamide] (L1 ) has been prepared from 1,2-bis(o-aminophenoxy)ethane, anti-chloroglyoxime. The new complexes derived from L1 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 ºC temperature. The ligand1:metal:ligand2 ratio of these complexes have been found to be 1:2:2. The new Cu(II), Ni(II), Co(II) and Cd(II)complexes of these ligands are proposed to be octahedral. These new complexes have beencharacterized by elemental analyses, molar conductivity, magnetic susceptibility, IR, 1H-NMR, UVVis spectra and TGA techniques
