以L-丙氨酸或L-亮氨酸及水杨醛、乙酸锌为原料,通过无溶剂一步法合成了氨基酸水杨醛席夫碱锌(Ⅱ)配合物[ZnL(H2O)].nH2O(L=sal-ala,sal-leu),用EDTA滴定法、元素分析、红外光谱、X射线粉末衍射、热分析等手段对配合物的组成和结构进行了表征。结果表明,锌分别与席夫碱配体中的亚氨基氮、羧基氧、酚羟基氧以及水分子中的氧形成了配位数为4的配合物,其热分解包括失水、配体的氧化分解过程,最后完全分解为氧化锌。 Zinc (Ⅱ) complex of amino acid salicylaldehyde Schiff base [ZnL (H2O)] nH2O (L) was prepared by solvent-free one-step reaction using L-alanine or L-leucine and salicylaldehyde and zinc acetate = sal-ala, sal-leu), the composition and structure of the complex were characterized by EDTA titration, elemental analysis, IR, XRD and thermal analysis. The results show that zinc complexes with imino nitrogen, carboxyl oxygen, phenolic hydroxyl oxygen and oxygen in water respectively to form a coordination number of 4. The thermal decomposition includes dehydration, ligand Oxidative decomposition process, the final complete decomposition of zinc oxide.
