'''Dichlorine monoxide''', Cl<sub>2</sub>O, is a [[chlorine oxide]].
Dichlorine monoxide is the [[anhydride]] of [[hypochlorous acid]]; it is related to [[hypochlorite]]s generally.
It is also the unstable decomposition product of [[calcium hypochlorite]], and in high concentrations presents the risk of [[Combustion|ignition]] by [[friction]] or static spark.
