Annette Spiekermann, Stephan D. Hoffmann, Thomas F. Fssler,*
Ingo Krossing, and Ulrich Preiss
Starting from elemental gold and germanium a five-step synthetic route leads to the mixed anionic
cluster [Au3Ge45]9 , as described by T. F. F"ssler et al. in their Communication on
page 5310 ff. [Au(PPh3)Cl], obtained from Au metal via tetrachloroauric acid, reacts
in solution with the Zintl phase K4Ge9, which had been synthesized from the elements
in a solid-state reaction. The unusual complex represents the largest Ge cluster known
so far, and some of the 45 Ge atoms exhibit extraordinary modes of Ge coordination.
