Characterization of ternary and quaternary metal hydrides by Raman spectroscopy appears to be rather scarce due primarily to the decomposition of the metal hydrides by the energy of the laser excitation source. We report the results of some recent room temperature Raman measurements collected with a 2–10 mW 488 nm laser source for M₂RuH₆ where M=Ca, Sr and Eu. The assignments from this study are combined with existing vibrational data for other metal hydrides.
