希土二氯醋酸盐与邻菲罗啉(phen)混配配合物合成和表征

SYNTHESIS AND CHARACTERIZATION OF MIXED LIGAND COMPLEXES OF RARE EARTH DICHLOROACETATE WITH 1,10-PHENANTROLINE

本文采用一种新的合成方法在水、乙醇和四氢呋喃混合溶剂中合成了6种希土二氯醋酸盐与邻菲罗啉(phen)混配配合物,通过元素分析、红外光谱、差热-热重和紫外光谱等分析测试手段研究了配合物的性质,并确定配合物的组成为:Ln(CCl_2HCOO)_3(phen)_2·2H_2O[Ln=Gd、Tb、Er、Yb]和Ln(CCl_2HCOO)_3(phen)_2·H_2O·C_2H_5OH[Ln=Pr、Nd].

Six solid ternary coordination compound's of rare earth dichloroacetatc with 1,10-phenanthroline were synthesized in aquo-organic solvents. They were charaterized by elemental analysis、 IR spectra, DTA-TG thermal analysis and UV spectra. The composition of these complexes are Ln(CCl2HCOO)3(phcn)2 · H2O · C2H5OH(Ln = Pr、 Nd) and Ln(CCl2 HCOO)3(phen)2·2H20(Ln = Gd、 Tb、 Er、 Yb).
