Structural characterization of a completely alkyl-substituted Al–Sb Lewis acid–base adduct

The Lewis acid–base adduct t-Bu3Al–SbMe3 (1), which was synthesized by reaction of equimolar amounts of t-Bu3Al and trimethylstibine SbMe3, was characterized by multinuclear NMR (1H, 13C) spectroscopy, elemental analyses as well as by single crystal X-ray diffraction.
