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。
In recent years, coordination polymers have been rapidly developed due to their structural diversity and their potential applications in catalysis, drug carriers and gas adsorption and desorption [1-3]. In this paper, a new one-dimensional supramolecular compound [Ni (phen) 3] 2 (1,2,4,5-H3BTC) 2 (1,2,4,5-H2BTC ) · 2H2O. X-ray single crystal diffraction analysis showed that the compounds belong to the triclinic system with P1 space group. The unit cell parameters are a = 1.2403 (3) nm, b = 1.2907 (3) nm, c = 1.4512 96.261 (5) °, β = 106.500 (6) °, γ = 105.061 (4) °, V = 2.1086 (8) nm3 and Z = 2. In this compound, [Ni (phen) 3] 2+ cations and [H3BTC] - and [H2BTC] 2- anions form a one-dimensional supramolecular chain structure by electrostatic attraction, intermolecular hydrogen bonds and intramolecular hydrogen bonds .
