摘要：

The next super model: The Au84+ core of [Au 20(SR)16] can be viewed as two non-conjugate 4-center-2-electron (4c-2e) tetrahedral Au4 superatoms. The four valence electrons are delocalized in each Au4 unit as 4c-2e σ-bonds. Chemical bonding analysis confirms that a 2e-superatom network exists in [Au20(SR)16] (see picture: Au-yellow, SR-purple, superatoms-tetrahedra/red), this model explains the properties of this species.
