Zusammenfassung:A golden opportunity: The total structure of a Au36(SR)24 nanocluster (see figure) reveals an unexpected face‐centered‐cubic tetrahedral Au28 kernel (magenta). The protecting layer exhibits an intriguing combination of binding modes, consisting of four regular arch‐like staples and the unprecedented appearance of twelve bridging thiolates (yellow). This unique protecting network and superatom electronic shell structure confer extreme stability and robustness.
