A cyanide is a chemical compound that contains the cyano group, -C≡N, which consists of a carbon atom triple-bonded to a nitrogen atom. Cyanides most commonly refer to salts of the anion CN, which is isoelectronic with carbon monoxide and with molecular nitrogen. Most cyanides are highly toxic.

A cyanide is a chemical compound that contains the cyano group, -C≡N, which consists of a carbon atom triple-bonded to a nitrogen atom. Cyanides most commonly refer to salts of the anion CN, which is isoelectronic with carbon monoxide and with molecular nitrogen. Most cyanides are highly toxic.
In organic chemistry compounds containing a -C≡N group are known as nitriles, and compounds that contain the -N≡C group are known as isocyanides. Organic nitriles and isocyanides are far less toxic because they do not release cyanide ions easily.
The dye Prussian blue was first accidentally made (it is presumed) around 1706, from substances containing iron and carbon and nitrogen, and the (then unknown) cyanide was formed during the manufacture of the dye. An iron-containing compound was found in Prussian blue and named "ferrocyanide", meaning "blue substance with iron", from Latin ferrum = "iron" and Greek kyanos = "(dark) blue". When ferrocyanide was analyzed, removing the iron from the...
