摘　　要：在乙醇-水溶液体系中，合成了4种稀土苯甲酸8-羟基喹啉固体配合物．通过元素分析、摩尔电导、紫外-可见光谱、红外光谱和热谱分析，研究了配合物的组成、性质、成键特征，同时试验其抑菌作用.这些配合物的共同组成是RE（BA）（hq）2·H2O（RE＝La，Nd，Y，Er；BA＝C6H5COO－；hq＝C9H6NO-）．Four new solid complexes of rare earth (Ⅲ) with benzoic acid (HBA) and 8-quinoli- nol (Hhq) were synthesized in ethanol-water solution. These complexes have a general formula RE (BA ) (hq), .H2O (RE=La,Nd,Y,Er; BA=C6H5COO-; hq=C9H6NO- ) . Their properties are investigated by elemental analysis, molar conductance, IR spectra, UV-Vis spectra and TG- DTA. The fungistatic effect of the complexes are also studied.
