Abstract The 1:1 mole ratio reaction of t-Bu3In with Sb(SiMe3)3 results in the formation of the Lewis acid-base adduct t-Bu3In • Sb(SiMe3)3 (1), while the dimeric compound [t-Bu2InSb(SiMe3)2]2 (2) is isolated from the 1:1 reaction of t-Bu2InCl with Sb(SiMe3)3. Both the 2:1 reactions of t-Bu2InCl with Sb(SiMe3)3 and t-Bu2InCl with 2 result in the formation of the mixed-bridge compound $$t{\text{ - Bu}}_{\text{2}} $$ (3), however, 1H NMR studies suggest that this compound is unstable in solution. Thermolysis of 1, 2, and t-Bu3Ga • Sb(SiMe3)3 (4) results in the formation of nanocrystalline InSb or GaSb through a β-hydride elimination pathway.
