Infobox disclaimer and references

Dichlorine monoxide, Cl2O, is a chlorine oxide.

Dichlorine monoxide is the anhydride of hypochlorous acid; it is related to hypochlorites generally.

It is also the unstable decomposition product of calcium hypochlorite, and in high concentrations presents the risk of ignition by friction or static spark.
