摘　　要：首次在室温条件下通过固相法合成了了铈水杨酸8-羟基喹啉三元配合物Ce(Hsal)2(hq)(hq-=C9H6NO-;Hsal-=C7H5COO-).产物经元素分析、红外光谱、X-射线粉末衍射、热重-差热分析等手段确定了配合物的组成、结构以及成键特征.X射线粉末衍射结果表明:8-羟基喹啉的加入使反应迅速完成,同时分析了可能的固相反应机理.抑菌实验表明该类配合物对常见的细菌和真菌有比较好的杀灭效果.Ternary mixed rare earth complexe Ce(Hsal)2 (hq) (hq=C9H6NO-;Hsal-=C7H5COO-)was synthesized by solid-state reaction of rare earth chloride with sodium salicylate and 8-hydroxyquinoline at room temperature. The complexe were characterized by elemental analyses, X-ray powder diffraction, FT-IR and TG-DTA. The results indicate that the addition of the 8-hydroxyquinoline made the reaction completed quickly. Antibacterial test show that the complex have strong antibacterial activity against Escherichia coli, Staphylococcus aureus, Candida albican, Bacillus subtilis.
