Abstract
Organophosphoryl polyoxotungstate derivatives α-[PhP(Y)]2X n +W11 (X n + = Ge4+, B3+; Y = O, S) have been obtained by the reaction of the monovacant α-[X n +W11O39](12− n )− (X n + = Ge4+, B3+) anions with PhP(O)Cl2 or PhP(S)Cl2 in acetonitrile. These new organic–inorganic hybrid anions have been characterized by elemental analysis, IR, 31P and 183W NMR spectroscopy. According to the elemental analysis and spectroscopic data, the hybrid anions consist of an α-[XW11O39] framework on which are grafted two equivalent PhP(O) or PhP(S) groups through P–O–W bridges. The six-line 183W NMR spectrum indicates that the hybrid anions possess C s symmetry in acetonitrile.
