Abstract
Reaction of the functionalized tetrel cluster [Ge9R3]–{R = Si(SiMe3)3} with coinage metal N-heterocyclic carbene (NHC) complexes affords the first Zintl cluster transition metal complexes coordinated by NHC molecules. In [(η3-Ge9R3)M(NHCDipp)], the D3d-symmetric cluster polyhedron coordinates with a triangular Ge3face to the coinage metals M = Cu, Ag, Au, which themselves also bind to the NHC. The role of fine tuning of electronic properties by using an NHC ligand is discussed for the transformation reaction of [(η3-Ge9R3)Ag(NHCDipp)] to yield [Ag(η3-Ge9R3)2][Ag(NHCDipp)2]. All complexes are fully characterized including single-crystal X-ray structure analyses.
