Carbon nitride
Carbon nitrides are compounds of carbon and nitrogen.
Covalent network compounds
- Beta carbon nitride - a solid with a formula β-C3N4, which is predicted to be harder than diamond.
- Graphitic carbon nitride - g-C3N4, with important catalytic properties
Azafullerenes
- Azafullerenes are a class of heterofullerenes in which the element substituting for carbon is nitrogen.[1] Examples include (C59N)2 (biazafullerenyl),[2] C58N2 (diaza[60]fullerene), C57N3 (triaza[60]fullerene) and C48N12.
Cyanofullerenes
- Cyanofullerenes are a class of modified fullerenes in which cyano- groups are attached to a fullerene skeleton. These have the formula C60(CN)2n, where n takes the values 1 to 9.
Cyanogen
- Cyanogen - C2N2 (NCCN)
- Isocyanogen - C2N2 (CNCN)
- Paracyanogen - a cyanogen polymer, (NCCN)n
- Paraisocyanogen - a cyanogen polymer, (CNCN)n
