摘要： 通过稀土金属的氢硼酸(B10H102-或者B12H122-)盐与DL-苯丙氨酸反应,合成了十八个氢硼酸苯丙氨酸合稀土金属(Ⅲ)螯合物。通过元素分析、红外光谱和摩尔电导率的测定确定了化合物的组成,并对化合物的热化学性质进行了研究,表明苯丙氨酸与稀土金属离子的螯合作用是通过氨基氮原子与羧羰基氧原子同稀土金属配位实现的。

Abstract: Eighteen new phenylalanine rare earth metal(Ⅲ) polyhedral borane chelates have been prepared in high yield by the reaction of rare earth metal hydroborate [Ln2(BnHn)3, n=10 or 12] with DL-phenylalanine. The products have been characterized by elemental analysis,IR spectra and electricalconductivity measurement. The results showed that in these compounds DL-phenylalanines are neutral ligands coordinated to rare earth ion through the nitrogen atom of amino group and the oxygen atom of carbonyl of carboxylic group.
