dc.description.abstractThe hexa-μ2-amido-tetraammine-tetraberyllium compounds [Be4(NH2)6(NH3)4]X2(X = Cl, Br, I, CN, SCN, N3) have been prepared from beryllium metal and NH4X or [Be(NH3)4]X2in liquid ammonia at ambient temperature. The obtained compounds feature an adamantyl shaped complex cation, which was examinedviaX-ray diffraction, IR, Raman and NMR spectroscopy. The speciation in solution was studiedvia15N labeling experiments supplemented with quantum chemistry. Hereby, the intermediates [Be2(NH2)(NH3)6]3+and [Be3(NH2)3(NH3)6]3+were identified. Reactivity studies provided bis(N-acetimidoylacetamidinato-N,N′)-beryllium(ii), when [Be4(NH2)6(NH3)4]2+was treated with acetonitrile. While the unprecedented octa-nuclear complex cation [Be8O(NH2)12(C5H5N)4]2+was received from pyridine. This cluster proves that the [Be4O]6+core can be stabilized without bidentateO-donor ligands.en
