Crystal Structure and Photoluminescent Property of an Asymmetric Ag(I) Binuclear Complex

We synthesized a new type of asymmetric binuclear Ag(I) complex, [Ag-2(dppaO(2))(2)(dppbz)] (1), consisting of two chelating dppaO(2)(-) ligands (dppaO(2)(-) = N,N-bis(diphenylphosphino)-amide-dioxide) and one bridging dppbz ligand (dppbz = 1,2-bis(diphenylphosphino)-benzene). According to X-ray crystal structure analysis, the two Ag(I) ions were adjacent to each other and were bridged by both the dppbz ligands and one of the oxygen atoms in the dppaO(2)(-) ligands. Complex 1 showed relatively strong green luminescence in the solid state.

Automated summary

We synthesized a new type of asymmetric binuclear Ag(I) complex, which showed relatively strong green luminescence in the solid state.
