摘　　要：以对甲基苯磺酸和碱式碳酸镍为原料,合成了对甲基苯磺酸镍,采用溶剂挥发法,得到了该配合物的晶体,用红外光谱、热重分析和X-射线单晶衍射等方法对其结构进行表征.在对甲基苯磺酸镍[Ni(H_(2)O)_(6)](p-CH_(3)C_(6)H_(4)SO_(3))_(2)的结构中,金属镍离子和6个配位水配位,形成畸形的八面体空间结构.磺酸基团中的氧原子与配位水形成氢键,对甲基苯磺酸基团以抗衡阴离子的形式存在.该配合物属于单斜晶系,P2(1)/n空间群,a=0.69564(14)nm,b=0.62968(13)nm,c=2.5176(5)nm,α=90°,β=91.420(4)°,γ=90°,V=110.24(4)nm^(3),Z=2.以Biginelli反应为探针,考察了对甲基苯磺酸镍的催化性能,证明其具有较高的催化活性.Nickel p-toluenesulfonate was synthesized from p-toluenesulfonic acid and basic nickel (Ⅱ)􀃭carbonate.The crystal of the complex was obtained with the solvent evaporation method.Its structure was characterized with IR,TG analysis and the X-ray single crystal diffraction methods.In the crystal structure of[Ni(H_(2)O)_(6)](p-CH_(3)C_(6)H_(4)SO_(3))_(2),Ni2+coordinates with six H_(2)O molecules,forming a deformed octahedral spatial structure.The O of SO_(3)-forms hydrogen bonds with H_(2)O.The p-Toluenesulfonate groups exist as counter anions.The complex belongs to the monoclinic crystal system,P2(1)/n space group,a=0.69564(14)nm,b=0.62968(13)nm,c=2.5176(5)nm,α=90°,β=91.420(4)°,γ=90°,V=110.24(4)nm^(3),Z=2.The catalytic property of nickel p-toluenesulfonate complex was investigated using Biginelli reaction as a probe,and the results showed that nickel p-toluenesulfonate has high catalytic activity.
