Speciation of Be2+ in acidic liquid ammonia and formation of tetra- and octanuclear beryllium amido clusters.
Ontology highlight
ABSTRACT: The 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]X2 in liquid ammonia at ambient temperature. The obtained compounds feature an adamantyl shaped complex cation, which was examined via X-ray diffraction, IR, Raman and NMR spectroscopy. The speciation in solution was studied via 15N labeling experiments supplemented with quantum chemistry. Hereby, the intermediates [Be2(NH2)(NH3)6]3+ and [Be3(NH2)3(NH3)6]3+
