Cl 2 O 6 is present as ionic chloryl perchlorate, ClO 2 ⊖ClO 4 ⊖ , in the crystalline state. This is not surprising in view of the chemical behavior of Cl 2 O 6 –it is used as perchlorate “supplier” for the synthesis of anhydrous perchlorates–but was not to be expected according to the results of earlier structural investigations. The Cl–O distance in the ClO 2 ⊕ion (ca. 141 pm) is much shorter than in the neutral ClO 2 in the gas phase. Each cation is coupled with two anions (and conversely) to give polymeric groups.
