Ytterbium(III) bromide

Ytterbium(III) bromide (YbBr<sub>3</sub>) is an inorganic chemical compound.

Refer to the adjacent table for the main properties of Ytterbium(III) bromide.

Preparation

Dissolving ytterbium oxide into 40% hydrobromic acid forms YbBr<sub>3</sub>·6H<sub>2</sub>O crystals. After mixing the hydrate with ammonium bromide and heating it in a vacuum, anhydrous YbBr<sub>3</sub> can be obtained.

Yb<sub>2</sub>O<sub>3</sub> + 6 HBr → 2 YbBr<sub>3</sub> + 3 H<sub>2</sub>O

Ytterbium(III) bromide can also be prepared by directly heating ytterbium oxide and ammonium bromide.
