摘要: 采用水热法合成了2个化合物{[Cu2(Hpimdc)(4,4’-bpy)]·H2O}n(1)和[Mn3(pimdc)2·6H2O]n(2)(H3pimdc=2-丙基-4,5-咪唑二甲酸,4,4’-bpy=4,4’-联吡啶),并对2个化合物进行了红外、元素分析、晶体结构和热稳定性分析。晶体结构分析发现化合物1之中的H3pimdc和4,4’-bpy交替与铜(Ⅰ)配位形成一维链线性铜(Ⅰ)配合物。沿a轴和(100)面去观察,2个一维链分子通过游离水连接而形成1个“U”型拓扑结构。而化合物2通过2-丙基-4,5-咪唑二甲酸链与锰(Ⅱ)连接为三维的网状结构。沿b轴方向,三维结构中存在交替的左/右手螺旋状二维结构。 |

Abstract: Two complexes, namely {[Cu2(Hpimdc)(4,4'-bpy)]·H2O}n (1) and [Mn3(pimdc)2·6H2O]n (2)(H3pimdc=2-propyl-4,5-imidazoledicarboxylic acid) have been designed, synthensized and characterized (X-ray single crystal analysis, thermal analysis and IR Spectrum) based on the imidazole ligand. In complex 1, 4,4'-bpy acts as a secondary ligands. The complex 1 forms one-dimensional (1D) linear geometry via Hpimdc2- and 4,4'-bpy. Because of the free water, the complex 1 which connected two linear structures via hydrogen bonds, forms a U-type topology geometry (along a axis and (100) plane). The single-crystal structure of 2 reveals that the compound exhibits a 3Dframework, which is generated from 2Dright- and left-handed helical chains alternating with the other 2Dhelical chains along the b axis.
