C70 fullerene is the
fullerene molecule consisting of 70
carbon atoms. It is a cage-like fused-ring structure which resembles a rugby ball, made of 25
hexagons and 12
pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge. A related fullerene molecule, named
buckminsterfullerene (C60 fullerene), consists of 60 carbon atoms.
