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).[1] It was discovered at 1993.[2] The bond angle of Br−O−Br is 111.7°, the bond angle of O−Br=O is 103.1°, and the bond angle of O=Br=O is 107.6°. The Br−OBrO2 bond length is 1.845Å, the O−BrO2 bond length is 1.855Å, and the Br=O bond length is 1.612Å.[3]

Reactions

Dibromine trioxide can be prepared by reacting a solution of bromine in dichloromethane with ozone at low temperatures.[1][4] It disproportionates in alkali solutions to [[bromide|BrШаблон:Su]] and [[bromate|BrOШаблон:Su]].[4]
