· Sm1 Mg2 Ni9

Sm₁Mg₂Ni₉ is an intermetallic compound belonging to the rare-earth nickel–magnesium family, characterized by a crystalline structure combining samarium, magnesium, and nickel in fixed stoichiometric ratios. This material is primarily of research and development interest for hydrogen storage and energy conversion applications, where rare-earth intermetallics are explored for their ability to absorb and release hydrogen under controlled conditions. The samarium-nickel base provides favorable thermodynamic and kinetic properties compared to purely nickel-based hydrides, making it a candidate for next-generation metal hydride batteries and fuel cell support systems, though industrial deployment remains limited.
