In a stable condition: The first example of a non-IPR hollow fullerene that is more stable than the IPR isomer has been reported for the C2v-C72 fullerene (see picture). This molecule has been trapped by the exohedral chlorination reaction that affords the #11188C72Cl4 molecule, the structure of which has been unambiguously determined by X-ray analyses.
