摘要
本文讨论了十四个镧系离子(除Pm以外)与α-α＇-联吡啶及三氯醋酸形成配合物的合成方法,并用类似的合成方法得到9个希土离子与α-α＇-联吡啶及三氟醋酸的混配配合物。通过元素分析,红外、紫外、差热和热重等分析测试手段,确定了两类配合物的组成分别为Ln(CCl_3COO)_3dipy·nH_2O(n=1-2)和Ln(CF_3COO)_3dipy,并讨论了它们的性质。
In this paper a new method of synthesizing all complexes of lanthanide (except Pm) with α,α' -dipyridine and trichloroacetic acid is presented. Nine complexes of rare earth, α,α' -dipyridine and trifluoroacetic acid has been prepared by similar method.The composition of these complexes are Ln(CCl3COO)3dipy·nH2O (n =1-2) and Ln(CF3COO)3dipy .They are characterised by elementary analysis, ultraviolet and infrared spectra. As well as thermogravimetric (TG) and differential thermal analysis (DTG).
