Ultrahigh-pressure crystallographic passage towards metallic hydrogen
Nature, Published online: 14 May 2025; doi:10.1038/s41586-025-08936-wThe observation of the transition from hcp H2 to a post-hcp structure with a six-fold larger supercell at pressures above 212 GPa is reported, indicating the trend of H2 polymerization through molecular association.
