Abstract

Organothiophosphoryl polyoxotungstates R2XW11O39n , R2P2W17O616 , R2PW9O345 , (X = P, Si, Ge, B or Ga; R = PhP(S), C6H11P(S)) have been prepared from lacunary polyoxoanions and PhP(S)Cl2 or C6H11P(S)Cl2. The products were characterized by elemental analysis, IR, P31 and W183 NMR spectroscopy. According to spectroscopic observations, the hybrid anions consist of a lacunary anion framework on which are grafted two equivalent C6H5P(S) or C6H11P(S) groups through P-O-W bridges. Some of the title compounds showed the antigerm activity.
