Dibromine trioxide is 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.[4]
Reactions
Dibromine trioxide can be prepared by reacting a solution of bromine in dichloromethane with ozone at low temperatures.[3][5]
It disproportionates in alkali solutions to Br−
and BrO−
3.[5]
