Cyanogen
Cyanogen is the
chemical compound with the
formula (
CN)
2. It is a
colorless, toxic
gas with a
pungent odor. The molecule is a
pseudohalogen. Cyanogen molecules consist of two CN groups – analogous to diatomic halogen molecules, such as
Cl2, but far less oxidizing. The two
cyano groups are bonded together at their
carbon atoms: N=C-C=N, although other isomers have been detected. Certain derivatives of cyanogen are also called "cyanogen" even though they contain only one CN group. For example
cyanogen bromide has the formula NCBr.

n.
cyanogen, poisonous gas (Chemistry)
Cyanogen
(n.)
A colorless, inflammable, poisonous gas, C2N2, with a peach-blossom odor, so called from its tendency to form blue compounds; obtained by heating ammonium oxalate, mercuric cyanide, etc. It is obtained in combination, forming an alkaline cyanide when nitrogen or a nitrogenous compound is strongly ignited with carbon and soda or potash. It conducts itself like a member of the halogen group of elements, and shows a tendency to form complex compounds. The name is also applied to the univalent radical, CN (the half molecule of cyanogen proper), which was one of the first compound radicals recognized.
