On the Chemistry of Gallium Compounds, II [1] . — Preparation and Structure of Bis(2,2,6,6‐tetramethylpiperidino)‐[tris(trimethylsilyl)silyl]gallium — ein First Example for a Monomeric Bis(amino)gallane with Gallium‐Silicon Bond The title compound tmp 2 GaSi(SiMe 3 ) 3 ( 4 ) (tmp = 2,2,6,6‐tetramethylpiperidino) was prepared by the reaction of (Me 3 Si) 3 SiLi · 3 THF ( 2 ) with tmp 2 GaCl ( 3 ). The NMR data ( 1 H, 13 C, 29 Si) and the crystal structure of 4 are discussed. It contains a trigonal planar‐coordinated gallium atom with long Ga‐N and GaSi bonds of 191 and 247 pm, respectively. This compound is the first fully characterized monomeric gallium bis(amide) and the second structurally investigated compound with a gallium‐silicon bond.
