The most important fullerene is buckminsterfullerene C60, obtained by leap-frog transformation of the fullerene C20. The second smallest fullerene obtained by leap-frog transformation is C72 (obtained from C24). It is surprising that C72 is unstable. The standard explanation of this fact is based on steric strain resulting from the existence of two hexagons, each surrounded by 6 hexagons. By analyzing the p-electron content, it is demonstrated that these hexagons show some »pentagon-like« behavior that may be the cause (or an additional cause) of the instability of C72. Hence, it is shown that there may be topological (non-steric) reasons for the instability of C72.
