We report the crystal structure of the thiolate gold nanoparticle [TOA+][Au25(SCH2CH2Ph)18 -], where TOA+ = N(C8H17)4 +. The crystal structure reveals three types of gold atoms:  (a) one central gold atom whose coordination number is 12 (12 bonds to gold atoms); (b) 12 gold atoms that form the verti...
