Fig. 1

a Innermost icosahedral Au12 shell. b Second icosahedral Au42 shell. c Third rhombicosidodecahedron-like Au60 shell. d Total structure containing an Au114 kernel and 24 [–SR–Au–SR–] staples. Rectangles are highlighted in magenta. e 24 quadrangles belonging to eight subunits produce eight equilateral triangles (marked in blue) in the third shell. f Substructure of the Au60 shell with a plane of symmetry. g Connecting centers of the adjacent rectangles in the third shell produces a regular octahedron (marked in magenta), along with eight equilateral triangles (marked in green) above its faces. Views along the [100] (h), [110] (i), [111] ( j) directions. Color labels in the chemical structures: Au, pink, blue, green, and orange; S, yellow. Aryl groups on thiolates are omitted for clarity.
