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 propertiesAzafullerenes 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 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 - C2N2 (NCCN)Isocyanogen - C2N2 (CNCN)Paracyanogen - a cyanogen polymer, (NCCN)nParaisocyanogen - a cyanogen polymer, (CNCN)nPercyanoalkynes, -alkenes and -alkanes

Although not a polyyne dicyanoacetylene otherwise fits within this series.
