Preparation and structure
editBarium 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
editBarium 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]
