Abstract
Heteropolynuclear gold(I)-thallium(I) complexes of the type [T1L n][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 {T1[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 nm) depending on the environment of the thallium(I) centres and on the nature of the N-donor ligand.
