摘要:
用乙二胺与乙酰丙酮、水杨醛反应合成了一种异双四齿席夫碱配体(H2L)及其铜、钴、镍、锌配合物,通过元素分析、红外光谱、紫外光谱、X射线光电子能谱等手段对配体及其配合物进行了结构表征.结果表明,推测所有配合物均为烯醇式四配位结构,确定新配合物的组成为MC14H16N2O2(M=Cu,Co,Ni,Zn).研究了配合物对双氧水的催化分解性能.

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.
