Resumen:
The stability of the ammonium phospho-molybdic Wells?Dawson-type salt (NH4)6P2Mo18O62.12H2O in various organic media was investigated at room temperature and 50 °C through infrared spectroscopy. The heteropoly-anion (P2Mo18O62)6− is soluble and stable in methanol, ethanol, 2-propanol, ethyl ether, acetone and acetonitrile. The alcohols dissociatively chemisorb on the anion forming alkoxy (methoxy, ethoxy and isopropoxy) species. The interaction with acetone and acetonitrile is nondissociative.
