摘要： 利用水和乙醇混合溶剂合成了稀土三氯醋酸盐与2份1,10-邻菲绕啉(phen)配合物RE(CCl3COO)3(phen)2·nH2O(RE=Nd,Sm,n=0;RE=Eu,n=2)的单晶.结构测定表明,Nd(CCl3COO)3(phen)2为三斜晶系,每个三氯醋酸盐均以双齿配位,2个phen亦为双齿配位,故配位单元中钕为10配位;Eu(CCl3COO)3(phen)2·2H2O为单斜晶系,1个三氯醋酸根在外界,2个三氯醋酸根为单齿配位,2个phen为双齿配位,另有2分配位水,故配位单元中Eu为8配位.

Abstract: The complexes of lanthanides(Nd, Sm, Eu) trichloroacetate(CCl3COO)3 with two 1,10-phenanthroline were synthesized in the mixed solvent of water and alcohol.The crystal structures of the two complexes Nd(CCl3COO)3 (phen)2 and Eu (CCl3COO)3 (phen)2· 2H2Ohave been determined by four-circle X-ray diffractometer.The Nd(CCl2COO)3(phen)2 belongs to triclinic system with space group P1.The coordination number of Nd is 10.The crystal Eu(CCl3COO)3(phen)2 · 2H2Obelongs to monoclinic system with space group P21/c.The coordination number of Eu is 8.

Key words: Lanthanide trichloroacetate, 1,10-Phenanthroline, Crystal structure
