Its composition was refined from X-ray and neutron powder diffraction data on the deuteride and found to be Mg2RhD1.1. The deuterium atoms in the structure occupy octahedral holes formed by Mg atoms and tetrahedral holes formed by Mg and/or Rh atoms. Retrieval of hydrogen by desorption destabilizes the structure and leads to a hitherto unknown binary metal compound of composition Mg2Rh which crystallizes with the Ti2Pd-type structure, a branch of the MoSi2-type structure.
