A cyanide is a chemical compound that contains the group C≡N. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom.In inorganic cyanides, the cyanide group is present as the anion CN−. Soluble salts such as sodium cyanide and potassium cyanide are highly toxic.
