摘要

A new DNS-based nickel sulfonate,[Ni(H2O)6](DNS)·2H2O(1)(DNS = 4,4'-dinitrostilbene-2,2'-disulfonic acid) has been synthesized and characterized by IR spectra,elemental analyses and single crystal X-ray diffraction.Compound 1 crystallizes in the triclinic system,space group P1,a = 6.802(5),b = 8.541(5),c = 11.830(5),α = 87.595(5)°,β = 75.724(5) °,γ = 85.771(5) °.Compound 1 exhibits a 3D supramolecular structure,which is constructed from metal-water chains and DNS anions via plenty of hydrogen bonding interactions.%本文利用4,4’-二硝基二苯乙烯-2,2’-二磺酸（DNS）,通过常规的方法合成了一个新的含有金属-水链的磺酸镍化合物,[Ni（H2O）6]（DNS）·2H2O（1）,并通过元素分析、红外光谱和X-射线单晶衍射方法对化合物的结构进行了表征.结构分析表明化合物1属于三斜晶系,P1空间群;晶胞参数：a=6.802（5）,b=8.541（5）,c=11.830（5）,α=87.595（5）°,β=75.724（5）°,γ=85.771（5）°.化合物1展示了一个由金属-水链与磺酸根阴离子通过氢键作用而形成的三维超分子结构.
