【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.更多还原

【Abstract】 The complexes of lanthanides(Nd, Sm, Eu) trichloroacetate(CCl3COO) 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· 2H2O have 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 · 2H2O belongs to monoclinic system with space group P21/c. The coordination number of Eu is 8.更多还原
