稀土乙酸8－羟基喹啉三元配合物的研究

Study on the Ternary Solid Complexes of Rare Earth with Acetic Acid and 8-Hydroxyquinoline

在乙醇水溶液体系中，合成了６种稀土（ＲＥ）乙酸（ＨＡｃ）８－羟基喹啉（Ｈｈｑ）三元固体配合物．通过元素分析、摩尔电导、红外光谱、紫外光谱、ｆ－ｆ跃迁光谱及热重－差热分析，确定了配合物的组成、性质和成键特征．所合成配合物的组成为ＲＥ（ＡＣ）（ｈｑ）２·Ｈ２Ｏ（ＲＥ＝Ｌａ，Ｎｄ，Ｓｍ，Ｈｏ，Ｅｒ，Ｙ），同时还试验其抑菌作用．

Six new solid complexes of rare earth (RE) with Acetic acid (HAc) and 8-Hydroxyquinoline (Hhq) are synthesised in ethanol-water solution. These complexes have the composition of RE (Ac) (hq)2·H2O (RE=La, Nd, Sm, Ho f Er, Y ). Their composition and properties are characterized by elemental analysis ,molar comductance, IR spectra, UV spectra, f-f transition absorptive spectra and T G-DTA measurements. The fungistatic effect of these complexes are also studied.
