Preparation of Nanocrystalline Indium Antimonide Through Beta-Hydride Elimination from New Indium-Antimony Single-Source Precursors
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 (I), while the dimeric compound T-Bu2InSb(SiMe3)22 (II) 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 (II) result in the formation of the mixed-bridge compound t-Bu2InSb(SiMe3)2In(t-Bu)2Cl (III), however 1H NMR studies suggest that this compound is unstable in solution. Thermolysis of I, II, and t-Bu3Ga.Sb(SiMe3)3 (IV) results in the formation of nanocrystalline InSb or GaSb through a beta-hydride elimination pathway.
