Six　new　silver(I)　complexes　with　diphosphine　ligands　and　1,10-phenanthroline　derivatives　are　named　by　[Ag-2(dppe)(dicnq)(2)](CF3SO3)(2)　(1),　Ag-2(dppp)(2)(dicnq)(2)](CF3SO3)(2)　(2),　Ag-2(dppp)(2)(dicnq)(2)](CF3SO3)(2)　(3),　[Ag(DPEphos)(dicnq)]CF3SO3　(4),　{[Ag(dppe)(dmp)](CF3SO3)center　dot(CH3OH)center　dot(H2O)(n))　(5),　[Ag-2(dppp)(2)(dmp)(2)]　(CF3SO3)(2)center　dot(H2O)　(6),　(dppe　=　1,2-bis(diphenylphosphino)ethane,　dppp　=　1,3-bis(diphenylphosphino)propane,　dppb　=　1,4-bis(diphenylphosphino)butane,　DPEphos　=　bis[2-(diphenylphosphanyl)phenyllether,　dmp　=　2,9-dimethyl-1,10-phenanthroline,　dicnq　=　6,7-dicyanodipyridoquinoxaline)　were　characterized　by　IR　and　X-ray　diffraction.　Further　fluorescence　spectroscopy,　photocatalytic　properties　and　terahertz　time-domain　spectra　(THz-TDS)　were　performed　on　2-6.　Complexes　1-3　and　6　were　binuclear,　while　4　was　mononuclear.　Complex　5　was　a　coordination　polymer,　displaying　a　one-dimensional　infinite　chain.　Moreover,　complexes　1,　2　and　4　were　assembled　via　several　pairs　of　C-H...pi　It　interactions　to　1D-3D　supramolecular　architectures.　The　emission　peaks　of　the　complexes　2-4　all　exhibit　a　large　degree　of　red　shift,　which　may　be　tentatively　attributed　to　the　intraligand　transition.　Compounds　2-6　represented　the　first　examples　of　Ag(I)　complexes　bearing　both　diphosphine　and　diimine　ligands　that　exhibit　high,　efficient　photocatalytic　abilities　for　dye　degradation　under　UV　light　and　show　good　stability　toward　photocatalysis.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
