Structure evolution spiral of the AuAg16(SR)12 cluster. The buildup of the structure of the organic monolayer-capped metallic AuAg16 cluster is shown starting from the central single gold atom in the middle and its encapsulation by 12 silver atoms (gray) in an AuAg12 icosahedron. Capping of the AuAg12 core through anchoring of organic benzene-containing molecules via sulfur-containing mounts (AuAg16S12) culminates in the formation of the monolayer-capped cluster AuAg16(SR)12, with the aromatic rings of the capping monolayer exhibiting unique dimer and trimer bundled structures.
