摘要/Abstract

摘要： Organothiophosphoryl polyoxotungstate derivatives α-C₆H₁₁P(S)]₂Xⁿ⁺W₁₁O₃₉^(8-n)- (X=P, Si, Ge, Ga)were obtained by the reactions of the monovacant α-[Xⁿ⁺W₁₁O₃₉]^(12-n)- (X=P, Si, Ge, Ga) anions with electrophilic C₆H₁₁P(S)Cl₂ in acetonitrile.These new organic-inorganic hybrid anions were characterized by elemental analyses, IR, ³¹P and ¹⁸³W NMR spectrometries.The six-line ¹⁸³W NMR spectrum indicates that [C₆H₁₁P(S)]₂Xⁿ⁺W₁₁O₃₉^(8-n)- (X= P, Si, Ge, Ga) anions possess true Cs 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-[XW₁₁O₃)] framework on which two equivalent C₆H₁₁P(S) groups are grafted through P-O-W bridges.
