    Description / Table of Contents: Reaction of tert.Butyl-lithium with Aluminiumtribromide; Molecular Structures of [HAl(CMe3)2]3 and [LiHAl(CMe3)3]2The reaction of tert.butyl-lithium with aluminiumtrihalide at low temperatures was reinvestigated. Four compounds were isolated: trimeric di(tert.butyl)alane(III) 1, monomeric (solution in benzene)/dimeric (solid state) lithium-tri(tert.butyl)alanate(III) 2, tri(tert.butyl)alane 3 and lithium-tetra(tert.butyl)alanate 4. X-ray structure analyses gave a planar sixmembered Al—H heterocycle for 1 and a Li—H-bridged dimer showing intramolecular interactions of lithium with C—H σ-bonds for 2.
    Notes: Die Reaktion des tert.Butyl-lithiums mit Aluminiumtrihalogenid bei tiefen Temperaturen wurde neu untersucht. Dabei isolierten wir: das trimere Di(tert.butyl)alan(III) 1, das monomere (benzolische Lösung)/dimere (Festkörper) Lithium-tri(tert.butyl)alanat(III) 2 sowie Tri(tert.butyl)alan 3 und Lithium-tetra(tert.butyl)alanat 4. Die Röntgenstrukturanalyse ergab einen planaren sechsgliedrigen Heterozyklus aus Al—H-Einheiten für 1 und ein über Li—H-Brücken verknüpftes Dimeres mit intramolekularen Wechselwirkungen zwischen den Lithiumatomen und C—H-σ-Bindungen für 2.
