Caesium tribromide is an inorganic compound with chemical formula Cs+
Br
3]−
. It can be obtained by crystallization from a concentrated aqueous solution of caesium bromide containing large amounts of bromine,[4] or by the hydrothermal reaction of caesium bromide, caesium bromate, and hydrobromic acid, in which bromine is generated in situ.[2]
It is isostructural with caesium triiodide and caesium diiodide bromide, and belongs to the orthorhombic Pmnb space group.[4]
It can oxidize some Au(I) complexes to Au(II) or Au(III) complexes.[1][5]
