This study investigates the effects of metal addition and doping of a 2-electron silver superatom, [Ag10 {S2 P(O i Pr)2 }8 ] (Ag10). When Ag+ is added to Ag10 in THF solution, [Ag11 {S2 P(O i Pr)2 }8 (OTf)] (Ag11) is rapidly formed almost quantitatively. When the same method is used with Cu+ , a mixture of alloys, [Cu x Ag11- x {S2 P(O i Pr)2 }8 ]+ ( x = 1-3, CuxAg11-x), is obtained. In contrast, introducing Au+ to Ag10 leads to decomposition. The structural and compositional analysis of Ag11 was characterized by single-crystal X-ray diffraction (SCXRD), ESI-MS, NMR spectroscopy, and DFT calculations...
