It is a dark brown solid which is stable below -40°C and is used in bromination reactions.〔 It is similar to dichlorine monoxide, the dioxide of its halogen neighbor one period higher on the periodic table. The molecule is bent, with C2v molecular symmetry. The Br-O bond length is 1.85Å and the Br-O-Br bond angle is 112°. A related diatomic molecule bromine monoxide (CAS#15656-19-6 ). ==Reactions== Dibromine monoxide can be prepared by reacting bromine vapor or a solution of bromine in carbon tetrachloride with mercury(II) oxide at low temperatures:〔〔 :2 Br2 + HgO → HgBr2·2H2O + Br2O It can also be formed by thermal decomposition of bromine dioxide or by passing an electrical current through a 1:5 mixture of bromine and oxygen gases.〔 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「Dibromine monoxide」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
