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

A novel substituted vic-dioxime ligand containing the amino group,n,n-[2,2-{ethane- 1,2-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 °c 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 been characterized by elemental analyses,molar conductivity,magnetic susceptibility,ir,1h-nmr,uvvis spectra and tga techniques.
