Abstract
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 BondThe title compound tmp2GaSi(SiMe3)3 (4) (tmp = 2,2,6,6‐tetramethylpiperidino) was prepared by the reaction of (Me3Si)3SiLi · 3 THF (2) with tmp2GaCl (3). The NMR data (1H, 13C, 29Si) and the crystal structure of 4 are discussed. It contains a trigonal planar‐coordinated gallium atom with long Ga‐N and GaSi 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.
