Synthesis and Biological Activity of Organothiophosphoryl Polyoxotungstates

Abstract

Organothiophosphoryl polyoxotungstates R_∋XW_∞∞O_∋∃^/- , R_∋ P_∋W_∞,O_∞^/-, R_∋PW_∃O_{∋ Δ}^-(X = P, Si, Ge, B or Ga; R = PhP(S), C₆H₁₁P(S)) have been prepared from lacunary polyoxoanions and PhP(S). The products were characterized by elemental analysis, IR, and NMR spectroscopy. According to spectroscopic observations, the hybrid anions consist of a lacunary anion framework on which are grafted two equivalent or groups through P-O-W bridges. Some of the title compounds showed the antigerm activity.
