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。
Two compounds {[Cu2 (Hpimdc) (4,4’-bpy)] · H2O} n (1) and [Mn3 (pimdc) 2 · 6H2O] n (2) were synthesized by hydrothermal method with H3pimdc = 2- 4,5-imidazole dicarboxylate, 4,4’-bpy = 4,4’-bipyridyl). The two compounds were characterized by IR, elemental analysis, crystal structure and thermal stability. Crystal structure analysis showed that H3pimdc and 4,4’-bpy in compound 1 alternately coordinated with copper (Ⅰ) to form one-dimensional linear copper (Ⅰ) complex. Observed along the a-axis and the (100) plane, two of the one-dimensional chain molecules are connected by free water to form a “U ” topological structure. While compound 2 is connected to manganese (II) via a 2-propyl-4,5-imidazolecarboxylic acid chain as a three-dimensional network. Along the b-axis, three-dimensional structures exist in alternating left / right hand helical two-dimensional structures.
