摘　　要：本文报道了镧、镨、铕、钇等元素分别与茜素红、邻菲咯啉和茜素红、喹啉生成三元配合物的制备方法,并通过化学分析、红外、紫外、热分析和溶解性能等测定,对所合成配合物的组成、结构以及性质等进行了研究。In this paper the solid coordination compounds composed of lanthanum, praseodymium, europium and yttrium with alizarin red S and 1,10-phcnanthroline or alizarin red S and quinolinc have been prepared, and their IR, UV, HNMR, thermal analyses, electric conductance and solubility in various solvents have been investigated. The ternary complexes were synthesized in water media of pH = 4.5-5.5 and 4-5 respectively. They arc soluble in dimethylsulfoxidc and dimcthylformamide, sparingly soluble in mcthanol and acetone, but insoluble in trichloromethanc, ether and water. Based on the testing results, the composition and structure of these compounds have been proposed.
