Infobox references

Barium hydride is a chemical compound with the chemical formula BaH
2.[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 + H
2 → BaH

## 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]
