Abstract

Neutron powder diffraction studies of beta-Co(OD)(2) to 16 GPa show that the structural changes with pressure are continuous and reveal no evidence for the amorphization of the hydrogen sublattice at 11 GPa previously proposed on the basis of light-scattering and x-ray diffraction studies [Nyugen et al., Phys. Rev. Lett. 78, 1936 (1997)]. Instead, the changes in the deuterium packing with pressure suggest that the observed anomalies in Raman andinfrared data at 11 GPa are the result of structural frustration due to H ... H repulsion.
