We have investigated the structural stability of the hydrides LiAlH4, NaAlH4, and NaBH4 under high pressure at room temperature using Raman spectroscopy. For all compounds studied we observe reversible structural phase transformations under pressure. The Raman results are not always compatible with the structures predicted by earlier theoretical calculations for the high-pressure phases, and further theoretical studies of the stability of NaBH4 under pressure have been carried out.
