Fullerene
Class of allotropes of carbon
A fullerene is an allotrope of carbon whose molecules consist of carbon atoms connected to form a closed cage. The molecules may have hollow sphere- and ellipsoid-like forms, tubes, or other shapes. The carbons are usually arranged in 5- and 6-membered rings.

From Wikipedia
A fullerene is an allotrope of carbon whose molecules consist of carbon atoms connected to form a closed cage. The molecules may have hollow sphere- and ellipsoid-like forms, tubes, or other shapes. The carbons are usually arranged in 5- and 6-membered rings. The family is named after buckminsterfullerene (C60), which in turn is named after Buckminster Fuller. C60 is also the first discovered and best characterized fullerene. C60 has a hollow sphere-like form, but other fullerenes are known with ellipsoid-like shapes. The closed fullerenes, especially C60, are also informally called buckyballs for their resemblance to the standard ball of association football. IUPAC defines fullerenes as "polyhedral closed cages made up entirely of n three-coordinate carbon atoms and having 12 pentagonal and (n/2-10) hexagonal faces, where n ≥ 20."
