A large variety of fluorinated benzene radical cations is isolated. The (crystal) structures show characteristic deviations from the neutral molecular structures. In some cases <i>Jahn-Teller</i>-distortians can be established. In a single case a dication is obtained.<br/>One electron oxidation of dialkyselenides and dialkyltellurides result in diamagnetic dimers of the radical cations in form of four membered rings. Dimerisation does not occur if perfluorinated diphenyl-disulfide and -diselenide are oxidized. By structural analysis and computational results it can be stated where the oxidation occurs in these cases.
