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] It is the theoretical anhydride of chlorous acid.
