'Carbon lone pair' HOMO]] A cyanide is any chemical compound that contains the cyano group (C≡N), which consists of a carbon atom triple-bonded to a nitrogen atom. Cyanide specifically is the anion CN-. Many organic compounds feature cyanide as a functional group; these are called nitriles in IUPAC nomenclature (for example, CH3CN is referred to by the names acetonitrile or ethanenitrile per IUPAC, but occasionally it is labeled using the common name methyl cyanide). Of the many kinds of cyanide compounds, some are gases, others are solids or liquids. Some are molecular, some ionic, and many are polymeric. Those that can release the cyanide ion CN- are highly toxic.
