heterofullerene 

Any compound formally derived from a fullerene by replacing one or more carbon atom by a heteroatom.

"Such heterofullerenes are expected to have applications
in superconductivity."

fullerene 

An allotrope of carbon with fused rings of five to seven atoms and a closed or partially closed mesh formed by carbon atoms joined by single and double bonds. The molecule may have the form of a hollow spherical, ellipsoid, tube, or something else entirely.

If collapse to a fullerene occurs before the cluster has accumulated 60 atoms, buckminsterfullerene can not be produced.

metallofullerene 

A molecule composed of a metal atom that is imprisoned inside a fullerene cage.

"Can someone name a type of fullerene?"
"Metallofullerene."
