title: Synthesis, structural characterization, and photophysics of dinuclear gold(II) complexes [(Au(dppn)Br)(2)](PF(6))(2) and [(Au(dppn)I)(2)](PF(6))(2) with an unsupported Au(II)-Au(II) Bond.
abstract: A series of novel dinuclear gold(II) complexes having an unsupported Au(II)-Au(II) bond with well-defined oxidation state at the gold center were synthesized. Red shifts in both the low-energy absorption and emission bands were observed upon increasing the donor ability of the coordinated halogen atoms.
