Plutonium trihydride is an compound of plutonium and hydrogen with the chemical formula PuH
3.[1][2][3]
Synthesis
Plutonium reacts noticeably with hydrogen at room temperature and rapidly when heated:[4]
- 2Pu + 3H
2 → 2PuH
3
- 2Pu + 3H
Also, heating of plutonium dihydride with hydrogen:
- 2PuH
2 + H
2 → 2PuH
3
- 2PuH
Physical properties
Plutonium trihydride forms grey crystals of hexagonal crystal structure[5][6], space group P63/mmc.
Chemical properties
When heated in an ammonia atmosphere, it forms a plutonium nitride:[7]
- PuH
3 + NH
3 → PuN + 3H
2
- PuH
It reacts with air:[8]
- PuH
3 + O
2 + N
2 → Pu
2O
3 + PuN + H
2
- PuH
