Isocyanogen, also known as cyanoisocyanogen, is a carbon nitride as well as a metastable isomer of cyanogen which has also been detected in the interstellar medium.
It is polar and is a ylide.
Isomers Besides the obvious isomer cyanogen, it also has another isomer, diisocyanogen.Diisocyanogen is the least stable of all isomers, and it polymerizes in solution at temperatures above -30 degrees celsius; despite this, its synthesis has been achieved.
However, unlike isocyanogen, it is nonpolar and has not been detected in the interstellar medium as of 2022.
