摘要 Organothiophosphoryl polyoxotungstate derivatives α-C_6H_(11)P(S)]_2X^(n+)W_(11)O_(39)^((8-n)-)(X=P, Si, Ge, Ga) were obtained by the reactions of the monovacant α-_2X^(n+)W_(11)O_(39)^((8-n)-)(X=P, Si, Ge, Ga) were obtained by the reactions of the monovacant α-[X^(n+)W_(11)O_(39)]^((12-n)-)(X=P, Si, Ge, Ga) anions with electrophilic C_6H_(11)P(S)Cl_2 in acetonitrile. These new organic-inorganic hybrid anions were characterized by elemental analyses, IR, (()^(31)P) and (()^(183)W) NMR spectrometries. The six-line ()^(183)W NMR spectrum indicates that [C_6H_(11)P(S)]_2X^(n+)W_(11)O_(39)^((8-n)-)(X=P, Si, Ge, Ga) anions possess true C_s symmetry in acetonitrile. According to the spectroscopic observation and the chemical analyses, it is known that each of the hybrid anions consists of an α-[XW_(11)O_(39)] framework on which two equivalent C_6H_(11)P(S) groups are grafted through P-O-W bridges.
