稀土－2，4，5－三氯苯氧乙酸配合物的研究

Study on the Complexes of Rare Earth with 2, 4, 5-Trichlorophenoxyacetic Acid

在水相中合成了三种新的稀土－三氯苯氧乙酸固体配合物，其通式为ＲＥ（ＴＣＲ）３（ＲＥ＝Ｓｍ３＋，Ｅｒ３＋，Ｈｏ３＋；ＴＣＰ－＝２，４，５－三氯苯氧乙酸）．并研究了它们的组成，溶解性，摩尔电导等物理性质，通过红外和紫外、可见光谱，热重和含热分析等手段，确定了配合物中ＲＥ３＋与ＴＣＰ－之间的成键特征．

Three solid complexal of rare earth with 2, 4, 5-trrichlorophenoxyacetic acid, general formula Re(TCP)3 (RE=Sm3+,Er3+Ho3+ ; TCP= 2, 4, 5-trichlorophenoxyacetic acid), are synthesized in aqueous phase. Their compositions and physicasl properties, such as solubility, molar conductance etc. are studied. The bonding characters which is between and TCP-are by means of IR spectra, UV spectra and their TG-DTA.
