摘要
近年来配位聚合物因其结构多样性及在催化、药物载体和气体吸附脱附等方面具有潜在的应用价值[1-3]而得到迅速的发展。本文在水热条件下,成功的合成出一例新型的一维超分子化合物,[Ni(phen)3]2(1,2,4,5-H3BTC)2(1,2,4,5-H2BTC)·2H2O。X-射线单晶衍射分析表明,化合物属于三斜晶系,P1空间群,晶胞参数为a=1.2403(3)nm,b=1.2907(3)nm,c=1.4512(3)nm,α=96.261(5)°,β=106.500(6)°,γ=105.061(4)°,V=2.1086(8)nm3,Z=2。在该化合物中,[Ni(phen)3]2+阳离子与[H3BTC]-和[H2BTC]2-阴离子通过静电引力、分子间氢键和分子内氢键,形成一个一维超分子链状结构。
Recently, coordination polymers rapidly expanded for their intriguing structural architectures and their potential applications in catalysis, drug delivery, gas sorption andstorage, and separation. A novel nickle compound [ Ni(phen) 3 ] 2 ( 1,2,4,5 - H3 BTC ) 2 ( 1,2,4,5 - H2BTC ) · 2H2O was successfully synthesized. X - ray single crystal diffraction analysis showed that the compound belonged to triclinic, P1 space group with the cell parameters a = 1. 2403(3) nm, b = 1. 2907(3) nm, c = 1.4512(3) nm, α =96.261 (5)°,β = 106. 500(6)°, γ = 105. 061 (4)°, V= 2. 1086(8) nm3, and Z =2. The compound was built up by [Ni(phen)3]2+, [H3BTC]-and [H2BTC]2- through electrostatic attraction, intermolecular hydrogen bond and intramolecular hydrogen bond to form 1 D chain structure.
