Abstract

Copper and Silver Clusters with Bridging Imido and Amido Ligands From the reactions of copper and silver chloride with tertiary phosphines and lithiated aniline the compounds [{Li(dme)3}4][Cu18(NPh)11] (1) and [Ag6(NHPh)4(PnPr3)6Cl2] (2) were obtained. The structure of the anion in 1 is closely related to the structures of the reported clusters [Cu12(NPh)8]4– [1] and [Cu24(NPh)14]4– [2]: 1 represents the third phenyl imido bridged copper cluster which contains parallel Cu3- and Cu6-planes. The dimeric compound 2 consists of two Ag3 units with bridging phenyl amido ligands. Two chloride and six phosphine ligands complete the ligand sphere and shield the metal core effectively.
