Chlorine perchlorate is the chemical compound with the formula Cl2O4. This chlorine oxide is an asymmetric oxide, with one chlorine atom in oxidation state +1 and the other +7, with proper formula ClOClO3. It is produced by the photolysis of chlorine dioxide at room temperature with 436 nm ultraviolet light:

2 ClO2 → ClOClO3

Chlorine perchlorate can also be made the following reactions at −45 °C.

CsClO4 + ClOSO2F → Cs(SO3)F + ClOClO3

Chlorine perchlorate is a pale greenish liquid which decomposes at room temperature.

Properties

It is less stable than ClO2 and decomposes to O2, Cl2 and Cl2O6 at room temperature.

2 ClOClO3 → O2 + Cl2 + Cl2O6

Chlorine perchlorate reacts with metal chlorides forming anhydrous perchlorates:

CrO2Cl2 + 2 ClOClO3 → 2 Cl2 + CrO2(ClO4)2 TiCl4 + 4 ClOClO3 → 4 Cl2 + Ti(ClO4)4
