Synthesis and characterization of organophosphorylpolyoxotungstate [ α2-R 2P 2W 17O 61] 6−(R=C 6H 11P(O), C 6H 5P(O), C 6H 11P(S), C 6H 5P(S))

Abstract

In the presence of Bu n 4NBr acting as a phase-transfer reagent, organophosphoryl derivatives of tungstophosphate of formula [ α 2-R 2P 2W 17O 61] 6− (R=C 6H 11P(O) ( 1); C 6H 5P(O) ( 2); C 6H 11P(S) ( 3); C 6H 5P(S) ( 4)) have been prepared and characterized by elemental analysis, IR, 31P and 183W NMR spectroscopy. The nine-line 183W spectrum indicates the hybrid anion possesses C s symmetry in CH 3CN–CD 3CN.
