Synthesis of molecular metallic barium superhydride: pseudocubic BaH12

Synthesis of molecular metallic barium superhydride: pseudocubic BaH12

Metallization of pure hydrogen via overlapping of electronic bands requires high pressure above 3 Mbar. Here the authors study the Ba-H system and discover a unique superhydride BaH12 that contains molecular hydrogen, which demonstrates metallic properties and superconductivity below 1.5 Mbar.
