Angew Chem Int Ed Engl. 2012 Dec 21;51(52):13114-8. doi: 10.1002/anie.201207098. Epub 2012 Nov 14.

Abstract

A golden opportunity: the total structure of a Au(36)(SR)(24) nanocluster reveals an unexpected face-centered-cubic tetrahedral Au(28) 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.
