Terbium(III) bromide explained

Terbium(III) bromide (TbBr₃) is a crystalline chemical compound.^[1]

Production and properties

Terbiun(III) bromide can be produced by heating terbium metal or terbium(III) oxide with ammonium bromide.^[2]

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).^[3]

Terbium(III) bromide is a white solid that is soluble in water.^[4] Its crystal structure is same as bismuth iodide.^[5]
