Ag ₁₂ [Ge ₉ (Hyp) ₂ ] ₆ An Intermetalloid Cluster with Bis‐Silylated Ge ₉ Units

Abstract We present the synthesis and characterization of the novel intermetalloid cluster compound Ag 12 [Ge 9 (Hyp) 2 ] 6 , exhibiting a silver core surrounded by bis‐silylated Ge 9 ‐clusters. The new intermetalloid cluster has an Ag 12 metal cluster core with silver atoms in different oxidation states. To the silver core six [Ge 9 (Hyp) 2 ] units are coordinated, acting as ligands. The [Ge 9 (Hyp) 2 ] units are arranged octahedrally around the Ag 12 core, leading to a variety of Ag‐Ge bonds and contacts. The cluster is a first example of an intermetalloid cluster, exhibiting a silver core, shielded by [Ge 9 (Hyp) 2 ] units.
