The title compound has been prepared in good yield by the reaction of galli
um trichloride with base-free hypersilyl lithium (Li-Si(SiMe3)(3), Me = CH3
) in a 1:3 molar ratio. Ga(Si(SiMe3)(3))(3) is monomeric in solution and in
the solid state. The compound has been characterized with NMR, IR and Rama
n techniques as well as by an X-ray structure determination (planar GaSi3-s
keleton, monoclinic space group P2(1)/c, Z = 4, d(Ga-Si) = 249,8 +/- 0,2 pm
).
