Tributylammonium pentatungstobis phenylphosphonate

These heteropoly salts are all white solids with similar IR spectra and well-resolved medium to strong peaks at 1130-970 cm " (P—O stretch) and 950-890 and 730-660cm (M—O terminal and bridging stretches). The ammonium and tetramethylammonium (sodium double) salts are soluble in water tributylammonium pentatungstobis(phenylphosphonate) is insoluble in water and methanol but soluble in acetonitrile, /V./V-dimethylformamide, dimethyl sulfoxide, and dichloromethane.
