Cyanocarbon
Cyanocarbons are a group of chemical compounds that contain several cyanide functional groups. Such substances generally are classified as organic compounds, since they are formally derived from hydrocarbons by replacing one or more hydrogen atoms with a cyanide group. The parent member is C(CN)4 (tetracyanomethane, also known as carbon tetracyanide). Organic chemists often refer to cyanides as nitriles.
