[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. (Figure Presented.)
