The bigger the more tubular? Structural characterization of Sm2§D3d(822)-C104 reveals that it is a member of a new class of nanocapsules with a carbon cage that resembles a small end-capped carbon nanotube. This remarkable molecule is the largest endohedral fullerene to be crystallographically characterized to date and is nearly twice the size of the prototypical C60.
