| 摘要: 利用不同溶剂合成并测定了希土三氯醋酸盐与α,α'-联吡啶(bipy)不同比例的配合物(Ⅰ)La:bipy=1:1,[La(CCl3COO)3(bipy)·H2O]2和(Ⅱ)Tb:bipy=1:2,Tb(CCl3COO)3(bipy)2·H2O,结构测定表明配合物(Ⅰ)与(Ⅱ)均为三斜晶系,中心离子La(或Tb)具有配位数为8的畸变四方反棱柱多面体;但是配合物(Ⅰ)形成具有对称中心的二聚体。 |

| Abstract: The complexes of lanthanide trichloroacctate with α,α'-bipyridine(bipy),(Ⅰ) La: bipy =1:1 [La(CCl3COO)3(bipy)·H2O]2,and(Ⅱ) Tb:bipy= 1: 2 TI(CCl3,COO),(bipy)2·H2O,were synthesized in the various solvents and determined by four-circle X-ray diffractometcr.Both complexes(Ⅰ)and(Ⅱ)are triclinic system with space group P1. The coordination number of central ion (La or Sm) is 8 with the slightly distortd square antiprism, but the complex(Ⅰ) forms a dimer with a central symmetry. |
