| 摘 要： | 以1,3-bip(1,3-二(咪唑基)丙烷),H2bpdc(4,4’-联苯二甲酸)和Ni(NO_3)_2·6H_2O为原料,在水热条件下合成了配位聚合物:Ni(1,3-bip)(bpdc)·0.5H_2bpdc]_n,并用红外光谱、热重分析、元素分析、粉末XRD和X-射线单晶衍射技术对配位聚合物的结构进行了表征.结构解析结果表明标题配位聚合物是一个具有五重穿插三维结构.其中,配位聚合物中每个Ni(Ⅱ)离子可被视作一个三连接的节点,通过拓扑计算,该配位聚合物的骨架具有(10~3)二硅化钍型拓扑结构.

| Abstract: | The title complexNi(1,3-bip)(bpdc)·0.5H_2bpdc]_n was synthesized from 1,3-bip(1,3-bis(imidazolyl)propane),H_2bpdc(biphenyl-4,4′-dicarboxylic acid)and Nickel nitrate hexahydrate by hydrothermal method and characterized by elemental analysis,IR and X-ray single crystal diffraction analysis.Single crystal X-ray analysis revealed that the title complex features a 3D→3Dfivefold interpenetrating framework.From the topological perspective,the Ni(Ⅱ)ions can be considered as a unimodal 3-connected node with a Schl?fli symbol of 10~3 ThSi_2 type topology. |
