Abstract

Reaction of [Ag(CF3CO2)] with [Au(C6X 5)(tht)] (X = halogen, tht = tetrahydrothiophene) leads to the synthesis of complexes [AgAu(C6F5)(CF3CO 2)(tht)]n (1), [Ag2Au(C6Cl 2F3)(CF3CO2)2(tht)] n (2), or [AgAu(C6Cl5)(CF3CO 2)(tht)]n (3), confirming the capability of a neutral complex, such as a perhalophenyl-(tetrahydrothiophene)gold(I), to act as electron density donor when treated with a Lewis acid substrate. All three crystal structures have been established by X-ray diffraction; all display Au⋯Ag and Ag⋯Ag interactions and polymeric 1D (2, 3) or 2D (1) networks built by means of additional Au⋯Au, Ag-O⋯Ag, or Au-S⋯Ag interactions. Complexes 1-3 are luminescent in the solid state at room temperature, and at 77 K or in frozen solutions they show a different luminescence in the solid state, which seems to be related to the different number and types of metal-metal interactions present in each case. DFT and TDDFT calculations on simplified model systems of 1-3 have also been carried out. © 2007 American Chemical Society.
