本论文报道了一个新的聚合物[Mg3(H2O)4(OH-)2(fum2-)2.2H2O]n(1)(H2fum为反丁烯二酸),该聚合物是在水热条件下合成的,并用单晶X-射线衍射,红外衍射,元素分析以及差热热重进行了表征。结构分析表明1是由棒状Mg-O-C次级结构单元构成的,平行排列的Mg-O-C棒状结构被有机配体连接在一起,构成一维的菱形孔洞,该孔洞被自由水填充着。对1进行拓扑结构分析表明,该聚合物具有三维的sra网络结构。
In this paper, a new polymer [Mg3 (H2O) 4 (OH-) 2 (fum2-) 2.2H2O] n (1) with H2fum as fumaric acid was reported. The polymer was synthesized under hydrothermal conditions Synthesized, and characterized by single crystal X-ray diffraction, infrared diffraction, elemental analysis and differential thermal gravimetry. Structural analysis shows that 1 is composed of rod-like Mg-O-C secondary structural units, and parallel Mg-O-C rod-like structures are connected by organic ligands to form one-dimensional diamond-shaped pores filled with free water. Topological analysis of 1 shows that the polymer has a three-dimensional sra network structure.
