Gold linkers: The first soluble gold–germanium cluster was obtained from the reaction of [Au(PPh3)Cl] and K4Ge9. The formation of the gold complex [Ge9Au3Ge9]5− (see picture) shows also an exciting result for gold chemistry: linearly coordinated gold atoms and the characteristics of aurophilic contacts between the metal atoms can be observed in the presence of polyanionic Zintl ions.
