Also known as ferric bromide, this red-brown odorless compound is used as a Lewis acid catalyst in the halogenation of aromatic compounds. It reacts with water to give acidic solutions. ==Structure, 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: :2FeBr3 → 2FeBr2 + Br2 Iron(III) chloride is considerably more stable, reflecting the greater oxidizing power of chlorine. FeI3 is not stable, as iron(III) will oxidize iodide ions. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Iron(III) bromide」の詳細全文を読む スポンサード リンク
