Focusing towards ternary metal hydrides has recently been regarded as a new avenue for research in pressure-dependent high-temperature superconductors, thanks highly to a fairly large number of permutations of alloying ...

We predict the existence of ternary pentahydride MgNiH5, adopting a hexagonal structure with a space group P63/mmc, at high pressure. Typically, the clarity of structural-phase stability could be demonstrated by thermodynamical ...
