By scattering X-rays from the compound, Hemley and colleagues showed that the material’s structure was consistent with LaH 10, which contains 10 hydrogen atoms for every lanthanum atom.

Closed electron shell systems, such as hydrogen, nitrogen or group 18 elements, can form weakly bound stoichiometric compounds at high pressures. An understanding of the stability of these van der ...
