Dichlorine trioxide, Cl2O3, is a chlorine oxide. It is a dark brown solid discovered in 1967 which is explosive even below 0 °C.[2] It is formed by the low-temperature photolysis of ClO2 and is formed along with Cl2O6, Cl2 and O2. Its structure is believed to be OCl−ClO2 with possible isomers such as Cl−O−ClO2.[3] The isomer having a structure of OCl–O–ClO would be the theoretical anhydride of chlorous acid.
