Synthesis and X-ray Crystal Structure of [Me<sub>2</sub>GaBi(SiMe<sub>3</sub>)<sub>2</sub>]<sub>3</sub>

[Me<sub>2</sub>GaBi(SiMe<sub>3</sub>)<sub>2</sub>]<sub>3</sub> (<b>1</b>) was synthesized in high yield by the equimolar reaction of Me<sub>2</sub>GaH and Bi(SiMe<sub>3</sub>)<sub>3</sub> and characterized by mass and multinuclear NMR spectroscopy and by single-crystal X-ray diffraction. [Me<sub>2</sub>GaBi(SiMe<sub>3</sub>)<sub>2</sub>]<sub>3</sub> represents the first Ga−Bi heterocycle, closing the gap on structurally characterized Ga−pnicogen compounds. The described reaction demonstrates the potential application of dialkylgallanes to serve as powerful synthons in organometallic syntheses requiring mild reaction conditions.
