Scheme 1. Schematic drawing of diazanaphthalene ligands used in the present study. The numbering of atoms used for NMR assignation follows the IUPAC rules and does not match the one applied in the X-ray and theoretical studies of gold(iii) complexes with these ligands. The α positions are numbered 1, 4, 5 and 8, while the β positions are 2, 3, 6 and 7.
