摘　　要：合成了钕、钇、镝、镥等稀土 (RE)·苯氧乙酸 (HPOA)·邻菲罗啉 (Phen)三元配合物。用化学分析法研究了它们的组成以及它们在不同溶剂中的溶解性能和摩尔电导等物理性质。用红外光谱、紫外光谱、热重一差热分析和 X射线粉末衍射等方法研究新合成三元配合物的结构及性质。确定了配合物中 RE3+与 POA-、Phen之间的成键特性。配合物通式为 RE(POA) 3· Phen,配合物中 RE3+为 8配位。Four new solid complexes of rare earth(III) with phenoxyacetic acid and 1,10 phenanthroline were synthesized ,and their composition,solubility and molar conductance were studied. The bonding characterstics between RE 3+ ,POA - and phen were established by means of IR spectra, UV spectra,TG DTA analysis and XRD technique. The formula of complexes is RE(POA) 3·Phen(RE=Nd,Gd,Dy,Lu,POA=phenoxyacetic acid; phen=1,10 phenanthroline),with 8 ligand number of RE 3+ .
