Abstract:
An unsymmetrical tetradentate Schiff base ligand (H2L) and its copper(Ⅱ),cobalt (Ⅱ),nickel(Ⅱ) and zinc(Ⅱ) complexes have been synthesized employing the reaction of ethylenediamine, acetylacetone and salicylaldehyde, and characterized by elemental analysis, IR, UV-VIS and XPS respectively. Based on the experimental results, a four-coordinated enol model was proposed for these complexes. The composition of new coordination compounds is MC14H16N2O2(M=Cu,Co,Ni,Zn).The catalysis properties of these complexes for decomposition of hydrogen peroxide has been studied.
