Heteropolynuclear gold(I)-thallium(I) complexes of the type [TlLn][Au(C6F5)(2)] (L = py (2), 2,2'bipy (3), 1, 10-phen (4) or 4,4'-bipy and THF (5); n = 1, 2) have been obtained from reactions of the corresponding N-donor ligands with the precursor {TI[Au(C6F5)(2)]}(n) (1). The crystal structures of complexes 3 - 5 have been determined by X-ray diffraction showing one-(3, 4) or three-dimensional (5) arrays. All complexes are photoluminescent in the solid state at RT and at 77 K. The strong visible emissions of complexes 2 - 5 are displayed over a wide range of wavelengths (460 - 620 =) depending on the environment of the thallium(I) centres and on the nature of the N-donor ligand.
