Carbon nitrides are compounds of carbon and nitrogen.

Contents

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. Examples include (C59N)2 (biazafullerenyl), 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

    • Percyanoalkynes, -alkenes and -alkanes

  • dicyanoacetylene - C4N2 [C2(CN)2], also called carbon subnitride or but-2-ynedinitrile
  • tetracyanoethylene - C6N4 [C2(CN)4]
  • tetracyanomethane - C5N4 [C(CN)4]
  • 2,2-diisocyanopropanedinitrile - C5N4 [C(CN)2(NC)2]
  • hexacyanoethane - C8N6 [C2(CN)6]
  • hexacyanocyclopropane - C9N6 [C3(CN)6]
  • hexacyanobutadiene - C10N6 [C4(CN)6]

    • Dicyanopolyynes

    Dicyanopolyynes are composed of a chain of carbon atoms with alternating single and triple bonds, terminated by nitrogen atoms. Although not a polyyne dicyanoacetylene otherwise fits within this series.
