Lewis Acid–Base Adduct Me3Sb–Ga(t-Bu)3

Abstract

The simple Lewis acid–base adduct Me3Sb–Ga(t-Bu)3 1 was prepared by reaction of t-Bu3Ga and SbMe3 in 1:1 M ratio. 1 was fully characterized by multinuclear NMR spectroscopy (1H, 13C). In addition, its solid state structure was determined by single crystal X-ray diffraction studies. 1 is monoclinic, space group P21 /n with a = 8.4895(2) A, b = 12.9303(4) A, c = 17.9976(5) A, β = 97.472(2)° and Z = 4. Me3Sb–Ga(t-Bu)3 was synthesized by the reaction of equimolar amounts of the weak Lewis-base Me3Sb and Ga(t-Bu)3. Me3Sb–Ga(t-Bu)3 represents a rather rare example of a Lewis acid–base adduct of trimethylstibine.
