摘要: 研究了稀土、铀、钍苦味酸盐与喹哪啶酸氮氧化物的配合作用,合成了组成为Ln_2(Pie)_3·(ANO)_3·3H_2O(Ln=La、Pr、Nd、Sm、Eu、Gd、Er、Y;Pic为苦味酸根离子;ANO-为喹哪啶酸氮氧化物阴离子)、UO_2(ANO)_2和Th(Pic)·(ANO)_3·5H_2O的固态配合物,并对配合物的组成,红外、紫外光谱,热稳定性,X射线衍射物相分析及摩尔电导等性质进行了测试和表征。

Abstract: The Solid coordination compounds of rare earth, uranyl and thorium picrates with quinaldinic acid N-oxide having the compositions Ln2 (Pic)3·(ANO)3·3H2O, UO2 (ANO)2 and Th2 (Pic)3·(ANO)3·5H2O (Ln = La,Pr,Nd,Sm,Eu,Gd,Er, Y;Pic- =picrate anions)are synthesized in non-aqueous solvents. These coordination compounds are characterized by elemental analysis, IR and UV spectra, X-ray powder diffraction analysis. Besides,the thermal stability and molar conductance of the coordination compounds are also discussed.
