三氟乙酰丙酮(HTTA)与稀土离子Y(Ⅲ)、Er(Ⅲ)和Nd(Ⅲ)配合物的合成及性质

STUDY ON SYNTHESIS AND PROPERTY OF SOME NOVEL COMPLEXES OF TRIFLUOROACETYLACETONE WITH REAR-EARTH ELEMENTS OF Y(Ⅲ)、Er(Ⅲ)and Nd(Ⅲ)

合成了三氟乙酰丙酮(HTTA)与稀土离子Y(Ⅲ)、Er(Ⅲ)和Nd(Ⅲ)的配合物,并测定了它们的配位数及稳定常数,结果显示这四种配合物的配位数均为3;它们的稳定顺序为:Er(TAA)3>Y(TAA)3>Nd(TAA)3。

Some novel complexes of trifluoroacetylacetylacetone with rear-earth elements of Y(Ⅲ)、Er(Ⅲ)and Nd(Ⅲ)were synthesized .And their property were checked .The result indicated that complexe number is 3.The sequence of their stability is as follow : Er(TAA)_3>Y(TAA)_3>Nd(TAA)_3.
