Two salts, dichlortetraquochromic bromide [(H2O)4CrCl2]Br and dibromtetraquochromic chloride [(H2O)4CrBr2]Cl.2H2O, have been described, as also has the compound, Cr2F2Cl4.
There is some reason for the belief that the interaction of chromic acid and acetyl bromide causes intermediate formation of unstable chromyl bromide, CrO2Br2. |
