Terbium(III) bromide

Terbium(III) bromide (TbBr3) 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.
 * Tb2O3 + 6 NH4Br → 2 TbBr3 + 6 NH3 + 3 H2O

A solution of terbium(III) bromide can crystallize 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 same as bismuth iodide.
