Structure of a missing-caged metallofullerene: La2@C72.
The La2@C72 metallofullerene having the so-called "missing" C72 fullerene cage was structurally elucidated by using 13C NMR and 139La NMR spectroscopy. The obtained structure of La2@C72 does not satisfy fullerene's structural golden rule, that is, the isolated-pentagon rule. The structure is consistent with a non-IPR D2-C72 (#10611) cage structure where each La atom is situated close to one of the two-fused pentagons.
