A different form of crystalline carbon is predicated over a molecule with sixty carbon atoms known as buckminsterfullerene (C60). The molecular form is spherical. Each and every carbon is bonded to three neighbours, as in graphite, and also the spherical form is obtained by a combination of 12 rings with 5 sides and twenty rings with 6 sides. Comparable constructions ended up very first visualized with the American architect R. Buckminster Fuller for geodesic domes.
