On the Chemistry of Gallium Compounds, IV. ‐ Synthesis and Structure of Monomeric (2,2,6,6‐Tetramethylpiperidino)‐gallanes Monomeric 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) 2 GaX ( 16, 17 , X=Cl, Br) various (aryloxy)‐ and organylbis (amido) gallium compounds (tmp) 2 GaY ( 18 – 21 , Y = OAr, Ph, Me) have been obtained. The crystal structures of (tmp) 2 GaOPh ( 18 ) and (tmp) 2 GaPh ( 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.
