摘　　要：本文制备了３－醛基水杨酸缩氨基硫脲铈（Ⅲ、Ⅳ）的配合物，通过元素分析、电导、红外、紫外和热谱等手段对配体和配合物的组成和性质进行了确定和表征，两种配合物的组成分别为ＣｅＡｃ１．５Ｌ１．５·４Ｈ２Ｏ和ＣｅＬ４·６Ｈ２Ｏ，同时测试了配体和配合物的抑菌活性。In this paper,3-formylsalicylic acid thiosemicarbazine and its Ce(Ⅲ,Ⅳ)complexes have been synthesised.The chemical compositions of two complexes are CeAc 1.5 L 1 5 ·4H 2O and CeL 4·6H 2O,respectively.Their properties have been investigated by element analysis,IR,UV,DTA-TG and molar conductance analysis.The synthesized ligand and its complexes have been evaluated for bacteriostatic activity against escherichia coli,staphylococcus aureus and bacillus subtilis.
