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

Preparation and structure

Barium hydride can be prepared by reacting elemental barium with hydrogen at relatively high temperatures between 150-200 °C:^[2]^{[clarification needed]}

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]
