Terbium(III) bromide ( Tb Br₃) is a crystalline

chemical compound A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element ...

Production and properties

Terbiun(III) bromide can be produced by heating

terbium Terbium is a chemical element; it has Symbol (chemistry), symbol Tb and atomic number 65. It is a silvery-white, rare earth element, rare earth metal that is malleable and ductile. The ninth member of the lanthanide series, terbium is a fairly ele ...

metal or terbium(III) oxide with

ammonium bromide Ammonium bromide, NH4Br, is the ammonium salt of hydrobromic acid. The chemical crystallizes in colorless prisms, possessing a saline taste; it sublimes on heating and is easily soluble in water. On exposure to air it gradually assumes a yellow ...

. : 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.CRC Handbook of Chemistry and Physics, 87th Edition, S. 4–94 Its crystal structure is the same as bismuth iodide.
