We shall classify the studies of mono- and polynuclear gold complexes according to the types of atoms coordinated to gold. The numbers incorporated into structural formulae show binding energies of core levels Cls, Nls, P2p, S2p, Au4f7/2, Ols, C12p3/2 for the respective atoms.

Further examples of emissive cyclometallated gold(III) complexes are [Au(L)Cl] (L = tridentate carbanion of 4 -(4-methoxyphenyl)-6 -phenyl-2,2 -bipyridine) [53], as well as mono- and binuclear bis-cyclometallated gold(III) complexes, namely [Au (C N C )L ]" (C N C = tridentate dicarbanion of 2,6-diphenylpyridine L = depro-tonated 2-mercaptopyridine (2-pyS ), n = 0 L = PPh3 or 1-methylimidazole, n = 1) and [Au2(C N C )2(P P)](C104)2 (P P = dppm, dppe) respectively [54]. The crystal structures of the binuclear derivatives show intramolecular interplanar separations of 3.4 A between the [Au(C N C)] moieties, implying the presence of weak n-n interactions. The mononuclear complexes show absorption with vibronic structure at 380-405 nm (e > 10 cm ), attributed to metal-perturbed intraligand transition.

A similar trend was observed in a series of mono-, di-, and trinuclear 2,5-dimethylphospholane (DMP) gold(I) complexes. Aurophilic interactions were estabUshed in the solid-state structures of the trinuclear gold(I) complexes [68], raising the question whether these secondary forces are responsible for the different catalytic behavior observed.
