A further sort of crystalline carbon is based over a molecule with sixty carbon atoms termed buckminsterfullerene (C60). The molecular condition is spherical. Just about every carbon is bonded to three neighbours, as in graphite, and also the spherical shape is obtained by a mix of 12 rings with 5 sides and twenty rings with 6 sides. Identical buildings have been first visualized through the American architect R. Buckminster Fuller for geodesic domes.
