Gadolinium(III) bromide is a crystalline compound of gadolinium atoms and bromine atoms. This salt is hygroscopic.[1]
Preparation
Gadolinium(III) bromide can be obtained by the reaction between gadolinium and hydrobromic acid:[5]
- 2 Gd + 6 HBr → 2 GdBr3 + 3 H2
The anhydrous form can be obtained by heating the hydrate with ammonium bromide.[5]
