AbstractNew gold(III) metallacyclic complexes with unprecedented aryl-carbene bidentate ligands have been prepared by the reaction of the cycloaurated gold(III) complex [AuCl 2(pap-C 1,N)] (pap = 2-(2-pyridylamino)phenyl) with isocyanide CNR (R = 2-naphthyl (1), cyclohexyl (2), or 2,6-dimethylphenyl (3)). Complexes have been spectroscopically and structurally characterized, showing in some complexes aurophilic gold(III)***gold(III) and π-π interactions. In contrast with the starting material these complexes are emissive in the solid state, probably because of the better σ-donor properties of the new bidentate ligands. © 2012 American Chemical Society.
