摘要：

The mono- and tetra-nuclear complexes [AU(PPh(3))(C7H5N2)] 1 and [{Au(PPh(3))(mu-C7H5N2)Cu(mu- C7H5N2)}(2)] 2, the latter containing 7-azaindolate (C7H5N2-) 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) Angstrom respectively. Extended-Huckel molecular-orbital calculations revealed a weak Au-1...Cu-1 bonding interaction but no Cu-1...Cu-1 interaction. In acetonitrile, both complexes display intense intraligand emission at 510 nm upon photoexcitation with UV/VIS fight at room temperature. In the solid state 2 shows an emission at 550 nm.
