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) Å, V = 3108.0(5) Å3, C29H23F3N2O3PSAg, Mr = 675.39, Z = 4, Dc = 1.443 g/cm3, F(000) = 1360, μ = 0.816 mm-1, the final R = 0.0675 and wR = 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) Å, α = 106.7120(10), β = 97.3830(10), γ = 113.027(2)°, V = 2441.2(4)Å3, 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 wR = 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. © 2015 Chinese J.
