One more type of crystalline carbon relies on a molecule with 60 carbon atoms referred to as buckminsterfullerene (C60). The molecular form is spherical. Each carbon is bonded to three neighbours, as in graphite, and also the spherical condition is accomplished by a combination of 12 rings with 5 sides and 20 rings with 6 sides. Very similar constructions ended up to start with visualized from the American architect R. Buckminster Fuller for geodesic domes.
