The one-electron oxidizing agent [NO]PF6 was reacted with Bu4N[Au(C6X5)(2)] (X = F, Cl) complexes in CH3CN. The gold(III) complexes [Au(C6F5)(3)(CH3CN)] and cis-[Au(C6Cl5)(2)(CH3CN)(2)]PF6 were synthesized by the oxidation of gold(I) to gold(III) with the concomitant ligand rearrangement "oxidative rearrangement". The supramolecular crystal packing in the perfluorinated aryl gold(III) complex is dictated by the notably short C(sp(2))-F center dot center dot center dot H(CH3CN) bond distance. The [Au(C6Cl5)(2)(CH3CN)(2)]PF6 complex exhibits antisymbiosis, displaying equal ligands in the cis position. The electrochemical oxidation of Bu4N[Au(C6X5)(2)] (X = F, Cl) complexes in CH3CN showed two irreversible peaks at 0.71 and 1.21 V (X = F) and at 0.65 and 0.91 V (X = Cl) vs Ag/AgCl.
