Abstract

Reducing (Ph<sub>3</sub>P)AuSC(SiMe<sub>3</sub>)<sub>3</sub> with l-Selectride® gives the medium-sized metalloid gold cluster Au<sub>70</sub>S<sub>20</sub>(PPh<sub>3</sub>)<sub>12</sub>. Computational studies show that the phosphine bound Au-atoms not only stabilize the electronic structure of Au<sub>70</sub>S<sub>20</sub>(PPh<sub>3</sub>)<sub>12</sub>, but also behave as electron acceptors leading to auride-like gold atoms on the exterior.
