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 metal or
terbium(III) oxide
Terbium(III) oxide, also known as terbium sesquioxide, is a sesquioxide of the rare earth metal terbium, having chemical formula . It is a p-type semiconductor, which conducts protons, which is enhanced when doped with calcium. It may be prepared ...
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 c ...

Solution of terbium(III) bromide can crystallize its hexahydrate. When heating it, it will dehydrate and produce some TbOBr.
Terbium(III) bromide is a white solid that soluble in water.
[CRC Handbook of Chemistry and Physics, 87th Edition, S. 4–94] It's crystal structure is same as
bismuth iodide
Bismuth(III) iodide is the inorganic compound with the formula Bi I3. This gray-black salt is the product of the reaction of bismuth and iodine, which once was of interest in qualitative inorganic analysis.
Bismuth(III) iodide adopts a distinc ...
