摘　　要：Two novel silver（I） complexes {[Ag（OTf）（PPh3）（4,4＇-bipy）]}∞（1） and {[Ag2-（OTf）2（dppb）3]（CH3CN）4}∞（2）（OTf = trifluoromethanesulfonate, PPh3 = triphenylphophine, 4,4＇-bipy = 4,4＇-bipyridine, dppb = bis（diphenylphosphino）butane） have been synthesized and characterized by IR, single-crystal X-ray diffraction, fluorescence spectrum and 1H NMR spectroscopy. Complex 1 crystallizes in orthorhombic, space group Pna21 with a = 19.259（2）, b = 9.85070（12）, c = 16.3827（17） A, V = 3108.0（5） A3, C29H23F3N2O3 PSAg, Mr = 675.39, Z = 4, Dc = 1.443 g/cm3, F（000） = 1360, μ = 0.816 mm-1, the final R = 0.0675 and w R = 0.1722 for 3662 observed reflections（I 〉 2σ（I））. Complex 2 crystallizes in triclinic, space group P1 with a = 12.9370（11）, b = 13.5261（13）, c = 16.4539（15） A, α = 106.7120（10）, β = 97.3830（10）, γ = 113.027（2）A, V = 2441.2（4）A3, C94H96F6N4O6P6S2Ag2, Mr = 1957.43, Z = 1, Dc = 1.331 g/cm3, F（000） = 1006, μ = 0.605 mm-1, the final R = 0.0717 and w R = 0.1795 for 5128 observed reflections（I 〉 2σ（I））. Complex 1 is of zigzag chain structure, in which each Ag atom is coordinated by one OTf- anion, two N atoms from two 4,4＇-bipy molecules and one P atom from PPh3 ligand. In 2, the central Ag atom is coordinated with one OTf- anion and three P atoms from three dppb ligands, which leads to the formation of a zigzag ring-bridge-ring chain with each ring consisting of two Ag atoms and two dppb ligands.Two novel silver（I） complexes {[Ag（OTf）（PPh3）（4,4＇-bipy）]}∞（1） and {[Ag2-（OTf）2（dppb）3]（CH3CN）4}∞（2）（OTf = trifluoromethanesulfonate, PPh3 = triphenylphophine, 4,4＇-bipy = 4,4＇-bipyridine, dppb = bis（diphenylphosphino）butane） have been synthesized and characterized by IR, single-crystal X-ray diffraction, fluorescence spectrum and 1H NMR spectroscopy.
