Abstract:
Procedures were developed for the synthesis of the guanidinium (Gua) and tetrabutylammonium (TBA) salts of 11-molybdotitano(IV)phosphate heteropolyanion (MTPH) from solutions with the stoichiometric ratio P : Mo = 1 : 11 and in excess of titanium(IV) ions, Ti : P ≥ 1.5, at pH 1.85–1.90. MTPH was isolated as the (Gua)5PMo11(TiO)O39 and (TBA)5PMo11(TiO)O39 salts. The composition and formula of MTPH were established by chemical analysis, electronic absorption spectroscopy in the visible region of the oxidized and reduced MTPH forms, IR spectroscopy, and 31P NMR. H5PMo11(TiO)O39, obtained by ion exchange of the Gua salt in an aqueous–organic medium, is a strong pentabasic acid. MTPH reacts with H2O2 to form a peroxo complex with limited stability in an aqueous solution. In aqueous–organic media, the peroxo complex is more stable. In acetonitrile, MTPH persists for several days.
