Synthesis, characterization and inelastic neutron scattering spectra of hydrogen insertion compounds of the mixed oxide V9Mo6O40

Hydrogen insertion compounds of V 9 Mo 6 O 40 have been synthesized and investigated using incoherent inelastic neutron scattering (IINS) vibrational spectroscopy. IINS spectra of H x V 9 Mo 6 O 40 (x=7.8 and 17.5) confirm that in both phases H is present as coordinated hydroxyl groups. There is no evidence for the presence of coordinated water in contrast to the hydrogen insertion compounds of MoO 3 and V 2 O 5 .
