Abstract

In the presence of Bu4NBr acting as phasetransfer reagent, organothiophosphoryl polyoxotungstate derivatives α-[RP(S)]2PW9(R=C6H5, C6H11) have been obtained by reaction of the trivacant β-[PW9O34]9- anions with electrophilic C6H5P(S)Cl2 or C6H11P(S)Cl2 in acetonitrile. These new organic-inorganic hybrid anions have been characterized by elemental analysis, IR, 31P and 183W NMR spectroscopy. The collective application of the spectroscopy data of these new species indicates that the hybrid anion consists of an α-[PW9O34] framework on which are grafted two RP(S) groups through P-O-W bridges. The five-line 183W spectra indicate that the hybrid anions possess Cs symmetry in acetonitrile.
