Barium hydride is a chemical compound with the chemical formula BaH2.[1]

Preparation and structure[]

Barium hydride can be prepared by dissolving elemental barium (Ba) with hydrogen at temperatures between 150-200 °C:[2]

Ba + H2 → BaH2

Reactions[]

Barium hydride reacts with oxygen and water. It is easily explosive when it is mixed with a solid oxidant such as a halide or chromate.[3]
