An arsenide hydride or hydride arsenide is a chemical compound containing hydride (H−) and arsenide (As3−) ions in a single phase. They are in the class of mixed anion compounds.
Arsenide hydride compounds may be produced by heating metal hydride and metal arsenide mixtures under pressure.[1]
Arsenide hydrides are under investigation as unconventional superconductors.[2]
The hydride ions can be replaced by fluoride or oxide ions to yield variations in composition.[3]
when heated to 800° CaFeAsH forms three phases.[4]
2CaFeAsH → Ca + CaFe2As2 + H2
