Charged species structurally related to several isomers of Cl 2 O 2 , of considerable importance in atmospheric chemistry, were obtained by chemical ionization (CI) and characterized by collisionally activated dissociation (CAD) mass spectrometry. The ClOClO + and [Cl 2 ‐O 2 ] + species were prepared by positive ion Cl 2 /CI of ClO 2 and O 2 , respectively, whereas the ClClO 2 + isomer proved an elusive species of considerably lower stability. The ClClO 2 − anion was obtained from the negative ion Cl 2 /CI of ClO 2 . The formation process, structure and stability of the ions are discussed in connection with available theoretical results and related to the recent preparation of (Cl 2 O 2 ) + SbF 6 − and (Cl 2 O 2 ) + Sb 2 F 11 − salts in the solid phase.
