In chemistry, chloryl refers to a triatomic cation with chemical formula ClO+
2. This species has the same general structure as chlorite (ClO−
2) but it is electronically different, with chlorine having a +5 oxidation state (rather than the +3 of chlorite). This makes it a rare example of a positively charged oxychloride. Chloryl compounds, such as FClO
2 and [ClO2][RuF6], are all highly reactive and react violently with water and most organic compounds.
