An additional method of crystalline carbon is based with a molecule with sixty carbon atoms referred to as buckminsterfullerene (C60). The molecular condition is spherical. Every single carbon is bonded to 3 neighbours, as in graphite, and also the spherical condition is achieved by a mixture of 12 rings with 5 sides and twenty rings with six sides. Very similar constructions were first visualized via the American architect R. Buckminster Fuller for geodesic domes.
