The mono- and tetra-nuclear complexes 1 and <2> 2, the latter containing 7-azaindolate (C7H5N2(1-)) bridging ligands, have been prepared and their crystal structures determined.The intramolecular Au...Cu and Cu...Cu separations in 2 are 3.0104(6) and 2.941(1) Angstroem respectively.Extended-Hueckel molecular-orbital calculations revealed a weak Au(I)...Cu(I) bonding interaction but no Cu(I)...Cu(I) interaction.In acetonitrile, both complexes display intense intraligand emission at 510 nm upon photoexcitation with UV/VIS light at room temperature.In the solid state 2 shows an emission at 550 nm.
