本文合成了邻氯苯甲酸与十五种稀土的配合物REL~3·H~2O(RE=Y,La~Lu,L=Clc~6H~4CO~2H),研究了它们的热分解及红外光谱.测定了钕、铽及镥三种稀土的配合物晶体结构,均属单斜晶系,空间群P2~1/n,稀土离子配位数为9,配合物呈无限链状聚合结构.

关键词: 晶体结构测定, 苯甲酸 P, 稀土金属络合物, 钕络合物, 镥络合物, 热分解, 铽络合物

REL3.H2O (RE = Nd, Tb, Lu, La, Ce, Pr, Sm, Eu, Gd, Dy, Ho, Er, Tm, Yb, Y; HL = o-chlorobenzoic acid) were prepared Their thermal decomposition and IR spectra were studied. The crystal structures of the Nd, Tb, and Lu complexes were determine by x-ray diffraction. They crystallize in the monoclinic space group P21/n and show infinite chain structures. The coordination no. of RE is 9.

Key words: CRYSTAL STRUCTURE DETERMINATION, BENZENECARBOXYLIC ACID P, RARE EARTH METAL COMPLEX, NEODYMIUM COMPLEX, LUTETIUM COMPLEX, THERMAL DECOMPOSITION, TERBIUM COMPLEX
