1,5-二苯基-1,3,5-戊三酮(H_2DBA)及邻菲咯啉(phen)、羟基离子([OH]^-)希土混配配合物的合成及性质研究

STUDY ON THE SYNTHESIS AND PROPERTIES OF THE SOLID COMPLEX COMPOUNDS OF RARE EARTH ELEMENTS WITH1,5-DIPHENYL-1,3,5-PENTANETRIONE, 1,10-PHENANTHROLINE AND HYDROXIDION

本文在乙醇-水溶液中合成了H_2DBA及phen、[OH]^-与希土离子的混配配合物Ln(HDBA)_2(OH)(phen)·H_2O(Ln=La、Pr、Nd、Sm、Eu、Gd、Tb、Dy、Ho、Er、Tm、Yb、Y)十三个.通过化学分析,元素分析及电导分析确定了配合物的组成;研究了配合物的紫外、红外光谱及热行为,并对可能的配合物结构进行了推测.

Thirteen mixed ligand coordination compounds were synthesized by the reaction of lanthanide ions (Ⅲ) (La、 Pr、Nd、 Sm、 Eu-Lu) with 1, 5- diphenyl- 1, 3, 5-phentanetrione(H2DBA), l,10-phenanthroline(phen) and hydroxidion([OH]-) in the ethanol-water solution. The complexes were characterized by elemental analysis, UV, IR spectra and thermal analysis. They can be formulated as Ln(HDBA)2(OH)(phen) · H2O and the lanthanide ion is seven coordinated.
