摘　　要：在水醇溶液中合成了标题配合物[Ni(phen)2.2H2O].Bsesa.NO3.2H2O,(phen=o-phenanthroline,BsesaH=2-Benzenesulfonylamino-ethanesulfonic acid),并进行了元素分析、红外光谱、X-射线衍射等表征。结果表明此配合物属三斜晶系,空间群为P墿,晶胞参数为:a=1.0358(0)nm,b=1.3853(8)nm,c=1.5157(4)nm,α=113.183(1)°,β=109.083(1)°,γ=96.385(1)°,V=1.829(2)nm3,Z=2,Dc=1.482 g/cm3,μ=0.714mm-1,F(000)=846。配合物中的金属镍离子与2个邻菲咯啉的4个氮配位,还与2个水分子配位,而形成六配位的变形八面体。配体苯磺酰牛磺酸中的氧原子没有配位而以抗衡阴离子存在。该配合物属离子型配合物,配合物通过静电引力和丰富的氢键构建为三维结构。The title complex was synthesized in water-ethanol solution and characterized by elemental analysis, IR spectroscopy and X-ray diffraction. The results showed that the title complex belonged to triclinie system with Pi space group and cell parameter：a = 1. 0358（0）nm,b = 1. 3853 （8） nm,c = 1. 5157（4） nm,α = 113. 183（0）° ,β = 109. 083（0）° ,γ =96. 385（0）°, V = 1. 829 （2） nm^3, Z = 2 ,De = 1. 482 g/cm^3 ,μ = 0. 714 mm^-1 , F（000 ） = 846. The complex formed distorted octahedral geommetry through coordination of N（ Ⅱ ） with four N atoms of two o-phenanthroline （ phen ） and two O atoms of two water molecule. It further constructed 3D supramolecular structure by abundance O-H … O hydrogen bonds between coordination water and sulfonic, between coordination water and nitrate radical, between crystal lattice water and crystal lattice water, between crystal lattice water and sulfonyl, and between crystal lattice water and nitrate radical.
