Antimony Oxybromides

Two oxybromides have been described: antimonyl bromide, SbOBr, obtained by the action of light and air upon a solution of antimony tribromide in carbon disulphide, and Sb4O5Br2, obtained either by hydrolysis of antimony tribromide, or by heating together antimony tribromide and absolute alcohol in a sealed tube. Antimonyl bromide is a brownish powder (the colour possibly being due to impurities) which on heating separates into two other substances. Continued heating converts it entirely into antimony trioxide. The compound Sb4O5Br2 may be obtained in the form of monoclinic crystals, or as a white powder, which decomposes on heating, yielding antimony tribromide and antimony trioxide.

While antimony tetrabromide does not appear to have been isolated, a complex compound of this substance with ammonium bromide has been obtained by adding successively bromine and ammonium bromide to a solution of antimony tribromide in hydrobromic acid. It forms black octahedra of composition corresponding to (NH4)2SbBr6. The rubidium salt, Rb2SbBr6, has also been obtained, in the form of black, pointed, hygroscopic prisms. It is decomposed by water.
