Terbium(III) bromide

Terbium(III) bromide (TbBr<sub>3</sub>) is a crystalline chemical compound.

Production and properties

Terbiun(III) bromide can be produced by heating terbium metal or terbium(III) oxide with ammonium bromide.

Tb<sub>2</sub>O<sub>3</sub> + 6 NH<sub>4</sub>Br → 2 TbBr<sub>3</sub> + 6 NH<sub>3</sub> + 3 H<sub>2</sub>O

A solution of terbium(III) bromide can crystallize as a hexahydrate. When heating the hexahydrate, it will dehydrate and produce some terbium oxybromide (TbOBr).

Terbium(III) bromide is a white solid that is soluble in water. Its crystal structure is the same as bismuth iodide.
