Direct observation of nucleus of lithium in a C60 fullerene cage by neutron diffraction study

The nucleus of the Li+ in a C-60 fullerene by a neutron diffraction study was closer to the inner wall of the fullerene cage than that of the center of its electron density, and the hyperconjugation interaction would arise between the vacant Li+ orbital and the pi orbitals of the hexagonal moiety of the C-60.

Automated summary

A neutron diffraction study revealed that the nucleus of Li+ in a C60 fullerene is closer to the inner wall of the fullerene cage than the center of its electron density. Additionally, a hyperconjugation interaction was observed between the vacant Li+ orbital and the pi orbitals of the hexagonal moiety of the C60.
