Abstract
We present the synthesis and characterization of the novel intermetalloid cluster compound Ag12[Ge9(Hyp)2]6, exhibiting a silver core surrounded by bis‐silylated Ge9‐clusters. The new intermetalloid cluster has an Ag12 metal cluster core with silver atoms in different oxidation states. To the silver core six [Ge9(Hyp)2] units are coordinated, acting as ligands. The [Ge9(Hyp)2] units are arranged octahedrally around the Ag12 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 [Ge9(Hyp)2] units. The reaction of K2Ge9(Hyp)2 (Hyp = Si(SiMe3)3) with phosphine stabilized silver halides gives the new intermetalloid cluster Ag12[Ge9(Hyp)2]6 exhibiting a novel Ag12 core surrounded by six [Ge9(Hyp)2] units acting as ligands. Within the Ag12 core two different kinds of silver atoms are present…
