Synthesis and Characterization of Tert-Butylgallium-Antimony Compounds; X-Ray Crystal Structures of t-Bu3Ga. Sb(SiMe3)3, T-Bu2GaSb(SiMe3)2, and t-Bu2GaSb(SiMe3)Ga(t-Bu)2Cl, The first Example of a Gallium-Antimony Mixed-Bridge Compound
Abstract
The 1:1 mole ratio reaction of t-Bu3Ga with Sb(SiMe3)3 in hexane yields the expected Lewis acid-base adduct t-Bu3Ga.Sb(SiMe3)3 (1). The 1:1 mole ratio dehalosilylation reaction of t-Bu2GaCl with Sb(SiMe3)3 yields the dimeric compound T-Bu2GaSb(SiMe3)22) (2). The mixed-bridge compound t-Bu2GaSb(SiMe3)3Ga(t-Bu)2Cl (3) was isolated from both the 2:1 reaction of t-Bu2GaCl with Sb(SiMe3)3 and the 2:1 equilibration of t-Bu2GaCl with 2. These new gallium-antimony compounds have been characterized through multinuclear solution NMR spectroscopy, partial elemental analysis, and single-crystal X-ray structural analysis. In addition, compound 2 was found to produce nanocrystalline GaSb with an approximate average particle size of 9 nm upon thermolysis at 400 deg C under vacuum.
