Cyanide - Wikipedia

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−. The word is derived from the Greek kyanos, meaning dark blue, as a result of its being
