本文合成了间甲基苯甲酸与十五种稀土元素的配合物REL3(RE=Y, Ln~Lu;HL=m~CH3C6H4CO2H), 研究了它们的红外光谱并测定了钕和铽两种稀土配合物的晶体结构, 两者均属单斜晶系, 空间群P2~1/n, 钕离子配位数为9, 铽离子配位数为8, 配合物均具有无限链状聚合结构。

关键词: 晶体结构测定, 红外分光光度法, 苯甲酸 P, 钇络合物, 钬络合物, 稀土金属络合物, 铈络合物, 镱络合物, 镨络合物, 镨络合物

ML3 (M = Y, La-Lu; HL = m-MeC6H4CO2H) were prepared and the Nd and Tb complexes were characterized by x-ray diffraction. Crystal data: monoclinic, space group P22/n, R = 0.030 and 0.036, resp. Nd is 9-coordinate and Tb is 8-coordinate and both have infinite chain structures.

Key words: CRYSTAL STRUCTURE DETERMINATION, INFRARED SPECTROPHOTOMETRY, BENZENECARBOXYLIC ACID P, YTTRIUM COMPLEX, HOLMIUM COMPLEX, RARE EARTH METAL COMPLEX, CERIUM COMPLEX, YTTERBIUM COMPLEX, PRASEODYMIUM COMPLEX, PRASEODYMIUM COMPLEX
