Resumen

The heteropolynuclear complexes [AuTl(C6X5) 2]n (X = F, Cl) react with dimethylsulfoxide (DMSO) in different molar ratios leading to products of stoichiometry [Tl 2{Au(C6F5)2}2{μ-DMSO} 3]n (1), and [Tl2{Au(C6Cl 5)2}2{μ-DMSO}2]n (2). These complexes have been structurally characterized and can be viewed as extended linear chains built with Tl-Au-Tl units in which the thallium atoms are bridged by the oxygen atoms of DMSO ligands. Additional [Au(C6X 5)2]- fragments interact with one or two thallium centres, respectively, giving rise to two different types of metal-metal interactions in each molecule. Both of them show a strong luminescence in solid state and complex 2 also in solution. The thallium-thallium interaction in this complex is considered to be the responsible of its luminescence, which remains in solution. © 2005 Elsevier B.V. All rights reserved.
