Fluoronium

The estimated^[1] structure and dimensions of H₂F⁺

The fluoronium cation, H₂F⁺, is a polyatomic ion formed by protonation or self-ionic dissociation of hydrogen fluoride:

HF + H⁺ → H₂F⁺

or

Unlike for halonium ions based on chlorine, bromine or iodine (chloronium, H₂Cl⁺, bromonium, H₂Br⁺, iodonium, H₂I⁺), hydrocarbyl derivatives of fluoronium, i.e. R₂F⁺, remain unknown.
