采用铜(Ⅱ)盐和邻香草醛缩氨基甲磺酸席夫碱以及4,4′-联吡啶在乙醇溶液中合成了具有三维网状的配位聚合物,通过元素分析、红外光谱对配位聚合物进行了表征,并利用X射线单晶衍射仪对其结构进行了鉴定。晶体结构分析表明,该标题配合物属单斜晶系,空间群P2(1)/c,晶胞参数为a=1.1956nm,b=0.8464nm,c=2.2166nm;α=90.00°,β=99.863(2)°,γ=90.00°,V=2.21(3)nm3,Z=2,Dc=1.431g.cm-3,F(000)=984,最终偏差因子R1=0.1031,wR2=0.2335和R1=0.2023,wR2=0.2855。 The coordination polymers with three-dimensional network were synthesized by copper (Ⅱ) salt, o-vanillin acetaminosulfonic acid Schiff base and 4,4’-bipyridine in ethanol solution. Through the elemental analysis, The polymer was characterized and its structure was identified by X-ray single crystal diffractometer. The crystal structure analysis showed that the title complex belongs to the monoclinic space group P2 (1) / c with unit cell parameters of a = 1.1956 nm, b = 0.8464 nm, c = 2.2166 nm, α = 90.00 °, 99.863 (2) °, γ = 90.00 °, V = 2.21 (3) nm3, Z = 2, Dc = 1.431g.cm-3, F (000) = 984, final deviation factor R1 = 0.1031, wR2 = 0.2335 and R1 = 0.2023, wR2 = 0.2855.
