For the two less stable isomers of cyanogen, the order of the atoms differs. Isocyanogen (or cyanogen cyanide) is {{chem2|-C\tN+\sC\tN}}.<ref>{{cite journal |doi=10.1021/j100191a027 |title=Central Bond in the Three CN.cntdot.dimers NC-CN, CN-CN and CN-NC: Electron Pair Bonding and Pauli Repulsion Effects |date=1992 |last1=Bickelhaupt |first1=F.

Addition of [[disulfur dichloride]] to cyanogen gives [[3,4-Dichloro-1,2,5-thiadiazole|3,4-dichloro-1,2,5-thiadiazole]].
