Iron(III) bromide is the chemical compound with the formula FeBr₃. Also known as ferric bromide, this red-brown compound is used as a Lewis acid catalyst in the halogenation of aromatic compounds. It reacts with water to give acidic solutions.

tructure, synthesis and basic properties

FeBr₃ forms a polymeric structure featuring six-coordinate, octahedral Fe centers.Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5.] Although inexpensively available commercially, FeBr₃ can be prepared by treatment of iron metal with bromine::2 Fe + 3 Br₂ → 2 FeBr₃

Above 200 °C, FeBr₃ decomposes to ferrous bromide::FeBr₃ → FeBr₂ + 0.5 Br₂FeCl₃ is considerably more stable, reflecting the greater oxidizing power of chlorine. And, following conventional trends, FeI₃ is less stable than the tribromide.
