Abstract:	The important role of supporting solvent in transmetallation reactions involving Grignard reagents is highlighted in the formation and crystallisation of the Group 13 ‘ate’ species, [Mg₃Br₃Cl₂(Et₂O)₆][GaPh₂Br₂] (1), [Mg₃Br₅(Et₂O)₆][InPh₂Br₂] (2), [MgBr(THF)₅][GaPh₃Br] (3), [MgBr(THF)₅][InPh₃Br] (4), [Mg(THF)₆][GaPh₂Br₂]₂ (5) obtained by reaction of PhMgBr with gallium and indium halides. The compounds have been characterised by ¹H NMR, elemental analyses, and single-crystal X-ray diffraction.
