HF).

At about 270 Pa of pressure and ambient temperature, the methane ion will react with neutral methane to yield methanium and a methyl radical:
:The methanium ion can also be made in the gas phase via the reaction of methane and an ion (i.e. a proton).

Stability and reactions

The cations obtained by reaction of methane with , including methanium, are stabilized by interactions with the HF molecules.
