Dissolving (PhCH2)3Ga (1) in THF yields the complex (2).Reaction of 1 with dry oxygen in toluene at -78 deg C leads to 2 (3), which is also formed from 1 and PhCH2OH.The salts K (5) and Cs (6) were obtained from (PhCH2)2GaCl (4) and KF or CsF, respectively, in acetonitrile.Crystal structures were determined for 2, 3, 6 and 2*toluene> (7).Gallane 2 is a chiral monomeric complex in the solid state.The benzyl substituents create a propeller-shaped molecule with a counterclock-wise orientation of the ligands. 3 and 7 are crystallizing as centrosymmetrical dimers with Ga2X2 rings >2 units with Cs-F contacts.In addition to the Cs-F interaction, the coordination of each Cs(1+) ion by two phenyl rings in a η6-fashion is observed.Key words: Gallium compounds / Gallane, tribenzyl- / Gallane, dibenzyl(benzyloxy)- / Gallate, dibenzyldifluoro-
