Plutonium (II) hydride , PuH ₂ is a chemical compound of plutonium with hydrogen . The compound belongs to the group of plutonium hydrides .

Extraction and presentation

Plutonium and hydrogen can react directly with one another between 100 and 200 ° C. The reaction product is then plutonium (II) hydride.

${\ displaystyle \ mathrm {Pu + H_ {2} \ {\ xrightarrow {100-200 \, {} ^ {\ circ} C}} \ PuH_ {2}}}$

It is extremely reactive to oxygen and water and can spontaneously explode in air. Plutonium (II) hydride can also react with nitrogen and carbon dioxide , but these reactions are slow. The compound has a hexagonal crystal structure and belongs to the non-stoichiometric compounds .
