Fig. 2. Schematic illustration of adsorption and activation of (a) –C O, (b) O2, and (c) solvated H+ on the Au13 core of [Au25(SR)18]− (a, b) or Au12Pt core of [Au24Pt(SR)18]2− (c). SR in (a) is –S-C2H4Ph (colour code: pink, core Au(0); blue, motif Au(i); golden, S; grey, C). SR in (b) is –S-CH3; two SR–[Au(i)–SR]2 motifs are removed for co-adsorption of O2 and CO (colour code: golden, Au; yellow, S; grey, C; light grey, H; red, O). The solvent molecules in (c) are tetrahydrofuran (THF) (colour code: golden, Au; red, Pt; yellow, S; green, H; light grey, C). (a) is reproduced with permission from ref. 91.
