Abstract

The infrared, Raman and inelastic neutron scattering spectra of the approximately tetrahedral ternary metal hydrides: Mg2NiH4, Rb3ZnH5 and their deuterides have been observed and assigned. This has enabled a comparison of some of the properties of the first row transition ternary metal hydrides.
