Cadmium bromide is the inorganic compound with the formula CdBr2. It is a white hygroscopic solid. It also can be obtained as a mono- and tetrahydrate.[2] It has few applications.

Preparation and structure

Cadmium bromide is prepared by heating cadmium with bromine vapor.[2] The tetrahydrate has been obtained by crystallization of the dibromide from aqueous solution. At 3.04 g/cm3, it is much less dense than the anhydrous material. According to X-ray crystallography, the tetrahydrate is a polymer of CdBr2(H2O)2 with bridging bromide ligands. There are two interstitial water molecules[3]
