Fig. 6. (a) Schematic illustration of the formation of Au25Ag2(SR)18 by adding two additional Ag atoms to [Au25(SR)18]−; reproduced with permission from ref. 156. Copyright 2015, American Chemical Society. (b) ESI-MS spectra of Au25−xMx(SR)18 formed by reacting [Au25(SR)18]− with the corresponding M(i)–SR/M(ii)–SR complexes (M = Ni, Pd, Pt, Cu, Ag, Cd, and Hg); reproduced with permission from ref. 58.
