摘要
在溶剂热的条件下,合成了两例金属-有机配位聚合物: {［Ni(H2O)2(1,3-BIP)2］·TFBDC}n(1) 和 {［Cu3(H2O)4(1,3-BIP)6］·(BTC)2·(H2O)15}n(2)(1,3-BIP为1,3-二(咪唑)丙烷,H2TFBDC为2,3,5,6-四氟对苯二甲酸和H3BTC为1,3,5-均苯三酸),并利用红外光谱、元素分析和X-射线单晶衍射等技术手段对其结构进行了表征。X-射线单晶衍射结果表明配位聚合物1呈现一维环形链构型,并通过分子间氢键作用进一步连接形成三维超分子网络结构。配位聚合物2呈现出(4,4)拓扑的二维层状结构。此外,研究了两例配位聚合物的热稳定性能。
Abstract
Two metal coordination polymers, namely {［Ni(H2O)2(1,3-BIP)2］·TFBDC}n(1) and {［Cu3(H2O)4(1,3-BIP)6］·(BTC)2·(H2O)15}n(2)(1,3-BIP is 1,3-bis(imidazole)propane, H2TFBDC is 2,3,5,6-tetrafluoroterephthalic acid and H3BTC is 1,3,5-benzenetricarboxylic acid) were prepared under solvothermal conditions, and characterized by IR spectra, elemental analyses and single crystal X-ray diffraction. The single crystal X-ray diffraction reveals that coordination polymer 1 exhibits a 1D loop-like chain structure, which are further linked by intermolecular hydrogen bonding to form a 3D supermolecular architecture. While, coordination polymer 2 exhibits a 2D layer with (4,4) topology. Furthermore, the stability property of coordination polymers 1 and 2 were also investigated.
