Fig. 1. (A) Schematic structure of Au11(PPh3)7(SCN)3 as shown by Malatesta et al.34 The black circles show the position of the Au atoms and the white circles show the position of the PPh3 or SCN groups (adapted from ref. 34 with permission from The Royal Society of Chemistry). (B) Model of the cuboctahedral gold core of Au55Cl8(PPh3)12 as proposed by Schmid et al.41 All spheres represent Au atoms. In the brackets the proposed positions of the protecting atoms, namely P and Cl, are shown (reproduced from ref. 41 with permission from WILEY-VCH, Copyright © 1981, WILEY-VCH Verlag GmbH & Co.
