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). The Br-O-Br bond is bent with bond angle 111.2° and the Br-O-BrO2 bond length is 1.85Å.
Reactions
Dibromine trioxide can be prepared by reacting a solution of bromine in dichloromethane with ozone at low temperatures. It disproportionates in alkali solutions to Br−
and BrO−
3.
