Not to be confused with chlorine monoxide.
Dichlorine monoxide is an inorganic compound with the molecular formula Cl2O. It was first synthesised in 1834 by Antoine Jérôme Balard,[2] who along with Gay-Lussac also determined its composition. In older literature it is often referred to as chlorine monoxide,[3] which can be a source of confusion as that name now refers to the ClO• radical.
