Dibromine monoxide is the chemical compound composed of bromine and oxygen with the formula Br2O. It is a dark brown solid which is stable below −40 °C and is used in bromination reactions.[1] It is similar to dichlorine monoxide, the monoxide 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 1.85 Å and the Br−O−Br bond angle is 112°,[2][3] similar to dichlorine monoxide.

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:[1][3]

2 Br2 + 2 HgOHgBr2·HgO + Br2O

It can also be formed by thermal decomposition of bromine dioxide[2] or by passing an electrical current through a 1:5 mixture of bromine and oxygen gases.[3]
