Carbon nitride. Carbon nitrides are organic compounds consisting only of carbon and nitrogen atoms.

Covalent network compounds 
These materials are organic semiconductors. Due to its hydrogen-bonding motifs and electron-rich properties, this carbon material is considered a potential candidate for material applications in carbon supplementation.
 Beta carbon nitride - a solid with a formula , which is predicted to be harder than diamond.
 Graphitic carbon nitride - , with important catalytic and sensor properties.

 Dicyanodiazomethane , the only  isomer studied experimentally
 Tricyanamide  -  monomer (has never been prepared yet)
 Dicyanocarbodiimide  - another  monomer (was detected in products of photolysis of triazido-s-triazine).

  - a combined triazole and triazine framework.
 MCN-12 () and MCN-13 ().

Azafullerenes 

 Azafullerenes are a class of heterofullerenes in which the element substituting for carbon is nitrogen. Examples include  (biazafullerenyl),  (diaza[60]fullerene),  (triaza[60]fullerene) and .

Cyanofullerenes 

 Cyanofullerenes are a class of modified fullerenes in which cyano- groups are attached to a fullerene skeleton. These have the formula , where n takes the values 1 to 9.
