摘要：

<正> A new series of hexatungstate compounds has been prepared recently in this laboratory. The starting material is white powdery tungstic acid,and its extraction solution by DMSO reacts with many transition metal carbonates to give the hexatungstates of the respective metallic ions coordinated by DMSO. Among them,the structures of hex-akis(dimethylsulfoxide)-manganese (Ⅱ) hexatungstate [{(CH3)2SO}6Mn] [W6O19](1) and hexakis(dimethyl sulfoxide)-copper(Ⅱ) hexatungstate [{(CH3)2SO}6Cu}][W6O19] (2) have been determined from three-dimensional x-ray diffraction data and are hereby reported.Both compounds (1) and (2) crystallize in the monoclinic space group C2/c. The u-nit cell parameters for compound (1) are α=16. 398(3),b= 15. 026(1) ,c= 17. 827(2) A,β=111. 84(2)°,Z=4;and those for compound (2) are α=19. 165(4) ,b=14. 131 (2),c=16. 626(4) A ,β=117. 40(2)°, Z= 4. Both structures were solved by direct methods. Full matrix least squares refinements of positional and anisotropic temperature factors based o
