Completely comprised of bonds formed by sp2 ​hybridization, they are often formed from graphene.
One type of these structures is synthesized by exposing malonate to a base in the Bingel reaction, and a pure solution of them exhibits a distinct purple color. These structures, that were first synthesized by Kroto, Smalley, and Curl, can be found in armchair, stair, or chiral varieties. Completely comprised of bonds formed by sp2 ​hybridization, they are often formed from graphene. These compounds can be double walled or single­ walled, as exemplified by nanotubes. For 10 points, name these hollow allotropes of carbon, the most well known of which being a soccer ball-like formation of 60 carbon atoms named after a certain American architect.
