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.
通过使用¹³C NMR和¹³⁹La NMR光谱对具有所谓“缺失”C72富勒烯笼的La₂@C72金属富勒烯进行了结构解析。所得到的La₂@C72结构并不满足富勒烯的结构黄金规则，即孤立五边形规则。该结构与非IPR D2-C72（#10611）笼结构一致，其中每个La原子靠近两个稠合五边形之一。
