Cyanogen fluoride (IUPAC name: carbononitridic fluoride) is an inorganic compound with the chemical formula FCN. The molecule of this compound is linear, having the structural formula F−C≡N. It consists of a fluorine atom in a single bond with a carbon atom of a cyano group. It is a toxic and explosive gas at room temperature. It is used in organic synthesis and can be produced by pyrolysis of cyanuric fluoride or by fluorination of cyanogen.
