稀土·2,4,5-三氯苯氧乙酸邻菲罗啉配合物的研究

Study on the Complexes of Rare Earth with 2,4,5-Trichl or ophenoxyacetic Acid and 1,10-Phenanthroline

在水相中合成三种新的稀土·三氯苯氧乙酸·邻菲罗啉固体配合物,其通式为RE(TCP)_3·phen(RE=La,Nd,Er;TCP=2,4,5-三氯苯氧乙酸;phen=1,10-邻菲罗啉)。研究了它们的组成,溶解性和摩尔电导等物理性质。通过红外光谱、紫外光谱和热重-差热分析等手段,确定了配合物中RE^(3+)与TCP^-,phen之间的成键特性。

Three new solid complexes of rare earth (Ⅲ) with 2,4,5-Trichlorophenoxyacetic Acid and 1,10-Phenanthroline were synthesized in aqueous solution and the formula is RE(TCP)3·phen (RE=La,Nd,Er;TCP=2,4,5-Trichlorophenoxyacetate;phen=1,10-Phenanthroline).The composition,solubility and molar conductance etc,are studied. The bonding characteristics between RES3,TCP- and phen are established by means of IR spectra,UV spectra and TG-DTA analysis.
