Resumo

By treatment of the polymeric species [AuTl(C6Cl 5)2]n with ketones or with acetylacetone and 4,4′-bipyridine, the new tetranuclear complexes [Au2Tl 2(C6Cl5)4]·L (L = PhMeC=O, acacH) or [Au2Tl2(C6Cl5) 4(bipy)]·(acacH) have been prepared. Their crystal structures have been determined by X-ray diffraction methods and they all present a central Au2Tl2 core formed via one Tl⋯Tl and four Au⋯Tl unsupported interactions resulting in a loosely bound butterfly cluster. These complexes are strongly luminescent in both the solid state and solution showing an optical behavior in agreement with the maintenance of the Tl⋯Tl contact even in solution. © 2005 American Chemical Society.
