[Ga₄{C(SiMe₃)₃}₄] with a Tetrahedral Ga₄ Skeleton

Abstract

The unusual oxidation state i and M4tetrahedral in the solid-state characterize tris(tri-methylsilyl)methylgallium, the disproportionation product of the reaction of Ga2Br4 · 2dioxane with solvent-free LiC-(SiMe3)3. Although only the monomeric unit is detected by mass spectrometry, tetramers (X-ray structure shown here) are found in the solid state.
