摘　　要：本文以苯磺酸钠和六水合硝酸钴为原料制得苯磺酸钴配合物。用红外光谱法对其组成和结构进行表征、X-射线单晶衍射法测定其晶体结构、热重分析法测定其热稳定性,X-射线粉末衍射测定其纯度。结果表明,其分子式为[Co(H_(2)O)_(6)](C_(6)H_(5)SO_(3))_(2),属于单斜晶系P2_(1)/n空间群,晶胞参数a=7.042(3)A,b=6.351(3)?,c=22.630(12)A,α=90°,β=93.987(6)°,γ=90°,V=1009.6(9)A^(3),Z=2,以Biginelli反应为例,考察了苯磺酸钴配合物的催化性能,实验结果表明,该方法具有原料和催化剂用量少,产率高,催化剂可重复使用等优点(CCDC:2165486)。The cobalt-benzenesulfonate complex was prepared with sodium benzene sulfonate and cobalt nitrate hexahydrate as raw materials Its composition and structure were characterized by infrared spectroscopy,its crystal structure was determined by X-ray single crystal diffraction,its thermal stability was determined by thermogravimetric analysis,and its purity was determined by X-ray powder diffraction.The results show that its molecular formula is[Co(H_(2)O)_(6)](C_(6)H_(5)SO_(3))_(2).It belongs to the Monoclinic crystal system,P 2_(1)/n space group;cell parameters a=7.042(3)A,b=6.351(3)A,c=22.630(12)A,α=90°,β=93.987(6)°,=90°,V=1009.6(9)A^(3),Z=2.Taking Biginelli reaction as an example,the catalytic activity of cobalt benzenesulfonate complex was investigated.The experimental results show that the method has the advantages of low consumption of raw materials and catalyst,high yields of products and repeatability of the catalyst(CCDC:2165486).
