Ho2O@D3(85)-C92: Highly Stretched Cluster Dictated by
a Giant Cage and Unexplored Isomerization
Posted on 2020-07-17 - 04:29
For endohedral metallofullerenes
(EMFs), it has been well established
that the cage shape and size should match those of the endohedral
cluster. As a result, sufficient cluster–cage interaction can
be achieved, which is essential for mutual stabilization. Nevertheless,
how a small endohedral cluster nests in a giant fullerene has been
less explored. Herein, we report a pair of large oxide-cluster fullerene
(OCF) isomers, denoted as Ho2O@C92-I and -II.
Crystallographic studies reveal that major isomer-I possesses a D3(85)-C92 cage with
a highly stretched Ho2O cluster inside, which contributes
to achieving regular metal–cage contacts. Density functional
theory (DFT) computations also reveal the predominant abundance of
the D3(85) isomer relative
to the other two possible minor species including C1(67) and C2(64) isomers. Moreover, electrochemical (EC) studies
verify that the isomers exhibit almost identical redox behaviors,
indicating their similar cage structures. On the basis of the remarkable
topological similarity of D3(85) and C1(67) isomers,
isomer-II is likely to be Ho2O@C1(67)-C92, though it remains to be confirmed.
Our studies thus provide new insights into the cage–cluster
interplay and cage isomerization, both contributing to a better understanding
of large EMFs.
