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.
