Preparation
Promethium(III) bromide can be obtained by reacting hydrogen bromide and promethium(III) oxide:[2]
- Pm2O3 + 6 HBr —500°C→ 2 PmBr3 + 3 H2O
Promethium(III) bromide hydrate cannot be heated to form its anhydrous form. Instead it decomposes in water to form promethium oxybromide:[3]
- PmBr3 + H2O(g) → PmOBr + 2 HBr
