Space-filling model of H2F+

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

HF + H+ → H2F+

or

3HF Template:Unicode H2F+ + HF2

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.
