Distonic ion

IUPAC RECOMMENDATIONS 2013
Distonic ion
Radical ion whose charge and radical sites are neither at the same atom nor in conjugation with each other. Note 1: For example, CH2-OH2+ is a distonic ion, whereas the molecular ion of methanol, CH3OH+ is a conventional radical cation. Note 2: In a valence bond description, ?-distonic ions have the charge and radical sites on adjacent atoms, ?-distonic ions are separated by one atom, ?-distonic ions by two atoms, and so forth.
