On the Chemistry of Gallium Compounds, IV. - Synthesis and Structure of Monomeric (2,2,6,6-Tetramethylpiperidino)-gallanesMonomeric dimethyl- and diethyl(2,2,6,6-tetramethylpiperidino) gallanes have been synthesized and spectroscopically characterized. Starting from bis(2,2,6,6-tetramethylpiperidino)gallium halides (tmp)2GaX (16, 17, X=Cl, Br) various (aryloxy)- and organylbis (amido) gallium compounds (tmp)2GaY (18-21, Y = OAr, Ph, Me) have been obtained. The crystal structures of (tmp)2GaOPh (18) and (tmp)2GaPh (20) show trigonal planar-coordinated gallium atoms. Planarcoordinated nitrogen atoms with a GaN bond length of 188 pm are present in 20. In contrast, 18 shows one planar- and one slightly pyramidal-coordinated nitrogen atom, and this results in two different bond lengths of 184.9 and 181.8 pm, respectively.
