Dichlorine pentoxide

Dichlorine pentoxide is a hypothetical chlorine oxide with a chemical formula Cl₂O₅. It remains unknown. Theory predicts that the perchloryl/chloride peroxide structure would be the most stable among various isomers of this molecular formula,[1] such as the anhydride of chloric acid or the chlorous acid/perchloric acid mixed anhydride.
