摘要： 为探讨钼多酸根阴离子在有机化学反应中的催化机理,用菲醌作底物合成了[(n-C4H9)4N]2[(OC14H8O)2Mo4O(10)(OCH3)2]配合物。X射线单晶结构分析表明,该晶体属单斜晶系,空间群P21/c,a=1.3149(5)nm,b=1.8666(8)nm,c=1.8903(3)nm,β=104.06(3)°,Z=2.收集到独立衍射点3505个,其中1382个为可观测点,最终一致性因子R=0.078.结构分析结果表明,菲醌与钼多酸根在不同的实验条件下,能形成配比、氧化态以及结构不同的配合物。

Abstract: To study the catalysis of polymolybdate,the title complex was synthesized by phenanthraquinone as the substrate,The molecular structure of the complex was determined by X-ray diffraction method.The crystal is monoclinic with space group P21/c,a=1,3149(5) nm,b=1.8666(8) nm,c=1.8903(3) nm,β=104.06(3)°,V=3.310(4) nm3,Z=2,Dc=1.521g/cm3.Independent reflections of 3505 were collected,in which 1382 were observed.The final R=0.078 and Rw=0.078.The result of structure analysis indicate that the complexes with different structures can be formed by phenanthraquinone as the ligand with the same polymolybdate under different experimental conditions.
