Attempted coordination of GaII with two new sterically bulky, aryl substituted bis(imino)pyridine ligands lead to Ga III species [2,6-{ArNCPh}2(NC5H 3)]GaI2+GaI4- (Ar = 2,5-tBu2C6H3, 2,6- iPr2C6H3 = Dipp) arising from thermodynamically favorable disproportionation reactions. Examination of these reactions lead to isolation of a neutral radical species [2,6-{DippNCPh} 2(NC5H3)]GaI2. Both EPR spectroscopy and DFT calculations on this compound indicate that the unpaired electron is localized in a di(imino)pyridine π* orbital of an anionic ligand with nearly zero contribution from the Ga or I centers. Reaction of {2,5- tBu2C6H3NCPh}2(NC 5H3) with AlCl3 yielded an analogous Al(iii) product, [{2,5-tBu2C6H3NCPh} 2(NC5H3)]AlCl2+AlCl 4-. The Royal Society of Chemistry 2010.
