摘　　要：以C6H5SO3H和NiCO3·2Ni(OH)2为原料,采用挥发法,在室温下合成了配合物[N(i H2O)6](C6H5SO3)2,通过红外光谱、X-射线单晶衍射和热重测定了[N(i H2O)6](C6H5SO3)2晶体空间结构和热稳定性.测试结果表明,[N(i H2O)6](C6H5SO3)2配合物属于单斜晶系,P2(1)/n空间群,a=6.9646(9)A,b=6.2868(9)A,c=22.324(3)A,α=90°,β=93.917(2)°,γ=90°,V=975.2(2)A3,Z=2,含有6个结晶水,且中心离子(Ni2+)并未与磺酸基发生直接配位.通过Biginelli反应为探针,考察了[N(i H2O)6](C6H5SO3)2配合物的催化性能.Nickel benzenesulfonate complex was synthesized with C6H5SO3H and NiCO3·2Ni(OH)2 by solvent evaporation method at room temperature.The structure and thermal stability of product were characterized by IR,X-ray single crystal diffraction and TG analysis methods.The result indicates that the complex belongs to monoclinic crystal system,P2(1)/n space group,a=6.9646(9)A,b=6.2868(9)A,c=22.324(3)A,α=90°,β=93.917(2)°,γ=90 °,V=975.2(2)A3,Z=2,the complex included six H2O,and the Ni2+didn’t coordinate directly with the sulfonic acid group.The catalytic performance of nickel benzenesulfonate complex was investigated using Biginelli reaction as a probe.
