Tetraalkyldistibanes Sb2R4(R =nPr,iBu) react withtBu3M (M = Al, Ga) at –30 °C with the formation of the Lewis acid–base adducts [tBu3M]2[Sb2R4] [M = Al, R =nPr (1),iBu (2); M = Ga, R =nPr (3),iPr4)]. Compounds1and2are stable in solution whereas3undergoes a Sb–Sb bond‐breakage reaction with the subsequent formation of [tBu2GaSb(nPr)2]2(5). The same trend was observed for the reaction of Sb2(iBu)4withtBu3Ga, which yielded the heterocyclic stibanylgallane [tBu2GaSb(iBu)2]2(6). In addition, the simple trialkylstibane adducttBu3Al–Sb(iBu)3(7) was obtained as a byproduct from the reaction of Sb2(iBu)4withtBu3Al. Compounds1–7were characterized by multinuclear NMR (1H,13C{1H}) and mass spectroscopy and elemental analysis. Compounds1,3,5, and7were also investigated by single‐crystal X‐ray diffraction.
