STUDY ON TERNARY COORDINATION COMPOUNDS OF LANTHANIDES(Nd^(3+),Ho^(3+),Er^(3+))WITH ACETYLSALICYLIC ACID AND DIANTTPYRYL METHANE

对Ln^(3+)(Nd^(3+)、Ho^(3+)、Er^(3+))—乙酰水杨酸(Asal)—二安替吡啉甲烷(DAM)体系的乙醇—水溶液的光度法研究和对固态钕配合物的元素分析确定,三元配合物的组成比为Nd^(3+):Asal:DAM=1:3:1;考查了该配合物的红外、紫外吸收光谱,热稳定性和溶解性;计算了相应配合物的超灵敏跃迁的振子强度,讨论了振子强度的增值与配体数目的关系。

The ternary coordination compounds of lanthanides (Nd^(3+), Ho^(3+), Er^(3+)) with acetylsalicylic acid (Asal) and diantipyryl methane (DAM) in agueous-ethanolic solvent system have been studied by spectrophotometry. The ratio of components in the coordination compound has been proved to be Ln^(3+): Asal: DAM=1:3:1. through spectrophotometric determination and elemental analysis of the coordination compound in solid state. The infrared and ultra-violet spectra, thermal stability and solubility of the coordination compound were investigated. The oscillator strength (p) of the corresponding coordination compounds have been calculated. The relation of the increment (△P) with the number of ligands was explained.
