Cyanogen is a compound of formula (CN) 2. It is a colorless gas at standard temperature and pressure. A cyanogen molecule consists of two CN groups bonded together at their carbon atoms (N≡C−C≡N). Cyanogen is the anhydride of oxamide. It can be generated from cyanide compounds and solutions of metal salts (such as copper(II) sulfate).
