Abstract

The IR and Raman spectra of two hydrated molybdates, MgMoO~4~ · H~2~O and MgMoO~4~ · 5H~2~O, were recorded and analysed. In both the compounds, bands indicating MoO octahedral coordination are observed. Three crystallographically different water molecules exist in MgMoO~4~ · 5H~2~O. MgMoO~4~ · H~2~O exhibits weak hydrogen bonds and MgMoO~4~ · 5H~2~O hydrogen bonds of medium strength.
