摘要:

合成钕、钆、镝、镥等稀土(RE)·2,4-二氯苯氧乙酸(HDCP)·邻菲罗啉(Phen)三元配合物。用化学分析法研究配合物的组成及其在不同溶剂中的溶解性能和摩尔电导等物理性质。用红外光谱、紫外光谱、热重-差热分析等方法研究新合成三元配合物的结构及性质。确定了配合物中RE³⁺与DCP-、Phen之间的成键特性。配合物通式为RE(DCP)₃· Phen(RE=Nd,Gd,Dy,Lu;DCP=C₈H₅O₃Cl₂ Phen=1,10-邻菲罗啉),配合物中RE³⁺为8配位。

Abstract:

Four solid ternary complexes of trivalent rare earth (neodymium,gadolinium,dysprosium,lutetium) with 2,4-Dichlorophenoxyacetic acid and 1,10-phenanthroline were synthesized. Their components and molar conductivity and solubility in different solvents were analyzed by chemical analysis.They were also characterized by infrared,ultraviolet and thermogravimetric analysis. Their composition was proved to be RE(DCP)₃ Phen (RE=Nd, Gd, Dy, Lu;DCP=C₈H₅O₃Cl₂) and the coordination number is 8.
