The C60 molecules, also called buckyballs, are rather powerful and Pretty much incompressible. Crystals are formed these that the balls are arranged in an fcc lattice with a just one-nanometre spacing amongst the centres of adjacent balls. The very similar C70 molecule has the shape of a rugby ball; C70 molecules also sort an fcc crystal when stacked with each other. The reliable fullerenes kind molecular crystals, with weak binding—furnished by van der Waals interactions—between the molecules.
