Abstract: The hydrothermal reaction of an aqueous solution of sodium molybdate, hypophosphorous acid, hydrochloric acid and N,N-dimethylformamide (DMF) gave rise to tetradimethylammonium tetrahydroxydotriacontaoxo(tetraoxophosphato)dodecamolybdate dihydrochloride tetrahydrate. The polyanion has a -Keggin structure, with P-O distances ranging from 1.535 (5) to 1.552 (5) Å and Mo-O distances from 1.664 (4) to 2.509 (4) Å.
