Ytterbium(III) bromide is an inorganic chemical compound with the formula YbBr3. It exists in the anhydrous solid. From aqueous solution, a hydrated form crystallizes .
Preparation Dissolving ytterbium oxide into 40% hydrobromic acid forms YbBr3·6H2O crystals. After mixing the hydrate with ammonium bromide and heating it in a vacuum, anhydrous YbBr3 can be obtained.林平娣, 吴国庆. 无水三溴化钐和三溴化镱的制备 [J]. 化学试剂, 1991(1):13-14. Yb2O3 + 6 HBr → 2 YbBr3 + 3 H2O
Ytterbium(III) bromide can also be prepared by directly heating ytterbium oxide and ammonium bromide.
