Dibromine trioxide is the chemical compound composed of bromine and oxygen with the formula Br2O3. It is an orange solid that is stable below −40 °C. It has the structure Br−O−BrO2 (bromine bromate).[2] The Br−O−Br bond is bent, with a bond angle of 111.2°, and the Br−O−BrO2 bond length[dubious – discuss] is 1.85Å.[3]
Reactions
Dibromine trioxide can be prepared by reacting a solution of bromine in dichloromethane with ozone at low temperatures.[2][3]
It disproportionates in alkali solutions to Br−
and BrO−
3.[3]
