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, �ĢCH2-OH2+ is a distonic ion, whereas the molecular ion of methanol, CH3OH+• is a conventional radical cation.
Note 2: In a valence bond description, α-distonic ions have the charge and radical sites on adjacent atoms, β-distonic ions are separated by one atom, γ-distonic ions by two atoms, and so forth.
