双咪唑基丁烷及邻苯二甲酸根构筑的镍多孔配位聚合物的合成、结构及性质研究(英文)

Synthesis,Structure and Properties of a Porous Ni(Ⅱ) Coordination Polymer Constructed from 1,1′-(1,4-Butanediyl)bis(imidazole) and o-Phthalate Acid

在水热反应条件下,合成了一种新的镍配位聚合物,[Ni(Pht)(bbim-4)]n(Pht=邻苯二甲酸阴离子,bbim-4=1,4-双(咪唑-1-基)丁烷),经元素分析、粉末X射线衍射、热重和X射线单晶衍射表征了配合物。该配合物属于单斜晶系,空间群C2/c。结构分析表明:该配合物是一个三维的具有三角形孔道的多孔配位聚合物。配位聚合物表现出一个整体上的铁磁行为。77 K温度下,气体吸附研究表明该多孔配位聚合物对N2和CO2气体的吸附具有选择性。

A coordination polymer [Ni（Pht）（bbim-4）]n （Pht=o-phthalate acid anion,bbim-4=1, 1＇-（1, 4-butanediyl）bis（imidazole） was synthesized by hydrothermal reaction and characterized by elemental analysis, powder X-ray diffraction, TGA and X-ray single crystal diffraction. The crystal belongs to monoclinic system, space group C2/c. Coordination polymer [Ni（Pht）（bbim-4）]n is a three-dimensional porous coordination polymer with triangular channels. The coordination polymer shows an overall ferromagnetic behavior. Gas sorption studies suggest that the coordination polymer has selectivity in adsorption of N2 and CO2 gas. CCDC： 818068.
