Chemistry:Isocyanogen
From HandWiki
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.[1][2]
Isomers
Besides the obvious isomer cyanogen, it also has another isomer, diisocyanogen.[3]
Diisocyanogen is the least stable of all C
2N
2 isomers, and it polymerizes in solution at temperatures above -30 degrees celsius; despite this, its synthesis has been achieved.[4][5]
However, unlike isocyanogen, it is nonpolar and has not been detected in the interstellar medium as of 2022.[6]
