The next super model : The Au 8 4+ core of [Au 20 (SR) 16 ] can be viewed as two non‐conjugate 4 center–2 electron (4c–2e) tetrahedral Au 4 superatoms. The four valence electrons are delocalized in each Au 4 unit as 4c–2e σ bonds. Chemical bonding analysis confirms that a 2e‐superatom network exists in [Au 20 (SR) 16 ] (see picture: Au yellow, SR purple, superatoms tetrahedra/red), this model explains the properties of this species.
