摘  要:以甲基磺酸和两种碱土金属氧化物为原料,合成了两个金属配合物[Mg(H_2O)_6](CH_3SO_3)_2·6H_2O(1)和Ca(CH_3SO_3)_2(2),通过X-射线单晶衍射和热重分析确定了配合物的晶体结构和热分解过程.结果表明,甲基磺酸镁含有12个结晶水,属于三方晶系,R 3空间群,a=9. 3230 (7)?,b=9. 3230 (7)?,c=21. 2017 (12)?,α=90°,β=90°,γ=180°,V=1595. 93(19)?~3,Z=3.甲基磺酸钙不含结晶水,属于正交晶系,Pbca空间群,a=10. 1298 (6)?,b=9. 2202 (5)?,c=17. 3274 (10)?,α=90°,β=90°,γ=90°,V=1618. 36 (16)?~3,Z=8.采用Biginelli作为探针反应研究其催化性能,证明甲基磺酸镁的催化性能优于甲基磺酸钙.Two metal complexes [ Mg( H2 O)6 ] ( CH3803 )2 ·6H2O ( 1 ) and Ca ( CH3 SO3 )2 (2) were syn- thesized by methanesultbnic acid and two alkaline earth metal oxides. The crystal structure and thermal decompo- sition of them were determined by X - ray single crystal diffraction technique and thermogravimetric analysis. The results show that the magnesium methanesulfonate has twelve crystal waters and belongs to the trigonal system, R 3space group, a=9.3230 (7) A, b=9.3230 (7) A, c=21.2017 (12) A, α =90°, β= 90°, γ=180°, V= 1595.93 ( 19 ) A, Z = 3. The calcium methanesulfonate has no crystal water and belongs to orthorhombic sys- tem, Pbca space group, a = 10. 1298 (6) A, b =9. 2202 (5) A,c = 17. 3274 (10) A, α =90°,β =90°,γ= 90°, V= 1618.36 (16) A3, Z = 8. Their catalytic performance was studied by using Biginelli as a probe reac- tion. The resuhs indicated that the catalytic activity of magnesium methanesulfonate is better than that of calcium methanesulfonate.
