在乙醇水溶液中合成了标题配位聚合物[Zn(phen)(H_2O)_3SO_4]·H_2O(phen=o-phenanthroline),并进行了元素分析、X射线衍射等表征.X射线衍射结果表明,此配合物属三斜晶系,空间群为P_1~-,晶胞参数为:a=0.8042(3) nm,b=0.8636(8) nm,c=1.1595(1) nm,α=92.067(0)°,β=92.126(0)°,γ=103.761(0)°,V=0.7809(0) nm~3,Z=2,D_c=1.016 g/cm~3,μ=0.876 mm~(-1),F_((000))=424.配合物中的金属锌离子与一个邻菲咯啉、3个水分子和一个硫酸根离子配位,形成一个变形的八面体结构,通过氢键构建为三维超分子配合物.
The title complex was synthesized by reaction of o-phenanthroline (phen) and zinc sulfate heptahydrate in water-ethanol solution. The crystal structure was characterized by X-ray diffraction, the complex composition was determined by elemental analysis, IR and UV spectrum. The results show that the title complex belongs to triclinic system with space group P_1~- and cell parameter: a=0.8042(3) nm,b=0.8636(8) nm, c=1.1595(1) nm, α=92.067(0)°, β=92.126(0)°,γ=103.761(0) °, V=0.7809(0) nm~3, Z=2, D_c=1.016 g/cm~3, μ=0.876 mm~(-1), F_((000))=424. The Zn(Ⅱ) is coordinated by one phen, three water molecule and one SO_4~(2-). The complex exhibites a distorted octahedron geommetry. 3D supramolecular structure is constructed by hydrogen bonds.
