Abstract

The caesium vanadium oxide phases Cs[V3O8] and Cs2[V6O16]·0.7 H2O were synthesized by a room temperature process, a promising alternative method to traditional routes to MV3O8 phases. The characterization of these compounds and Cs4[H2V10O28]·4H2O by powder X-ray diffraction, SEM and solid-state NMR is provided. In particular, we used 51V and 133Cs MAS NMR to investigate the local environment of caesium and vanadium nuclei and 2D 1H → 133Cs CP MAS HETCOR experiments to explore the spatial connectivities between caesium ions and water molecules in the interlamellar space. The results obtained on Cs2[V6O16]·0.7 H2O illustrate how powerful solid-state NMR can be to study structurally disordered materials.
