Covalent network compounds

Azafullerenes
  • Azafullerenes are a class of heterofullerenes in which the element substituting for carbon is nitrogen.[2] Examples include (C59N)2 (biazafullerenyl),[3] 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.
