A solution of terbium(III) bromide can crystallize a hexahydrate. When heating the hexahydrate, it will dehydrate and produce some terbium oxybromide (TbOBr).<ref>{{cite journal|journal=Journal of Inorganic and Nuclear Chemistry|volume=27|issue=9|language=en|date=September 1965|pages=1905–1909|doi=10.1016/0022-1902(65)80042-2|url=https://linkinghub.elsevier.com/retrieve/pii/0022190265800422|title=The thermal decomposition of rare earth and yttrium bromide hydrates|access-date=2020-05-29|author=I.
