Fullerene is a naturally occurring allotropy of carbon in which 60 carbon atoms are linked to form a stable structure.
This is the third allotrope of carbon discovered by Robert Curl, Harold Kroto, and Richard Smalley when they were studying certain long-chain molecules in the vicinity of red giant stars.
C-60 was named buckminsterfullerene because the molecular structure looks like a football or the domed roof of the stadium developed by American engineer Buckminster fuller.
Conclusion: Thus it was named buckminsterfullerene it is often called Buckyball (tiny soccer ball).
