The reactions of triphenylphosphine (PPh3) and 4,4′-bipyridine (bipy), 1,2-di(4-pyridyl)ethane (dpa), 1,3-bis(4-pyridyl)propane (bpp) ligands with AgX (X = BF4 and NO2) lead to five new complexes: {[Ag(PPh3)2(bpp)](BF4)}n (1), [Ag(dpa)(BF4)]n (2), {[Ag(PPh3)2(μ-bipy)]2(BF4)2}n(3) and {[Ag(PPh3)2(CH3CN)]2(μ-bipy)}(BF4)2(4) and [Ag(dpa)(NO2)]n (5). In 1, 2 and 3, the Ag atoms are bridged by pyridyl-containing ligands (bpp, dpa and bipy, respectively) to form infinite chain structure. In 4, the Ag atoms are bridged by bipyridine to form a dinuclear structure. Complex 5 is of layer structure which is formed by silver atoms, oxygen atoms from NO2− and dpa. All the complexes are characterized by X-ray diffraction, fluorescence and 1H NMR spectroscopy.
Five silver(I) complexes based on rigid and flexible pyridyl-containing ligands have been synthesized and characterized by elemental analysis, X-ray diffraction, 1H NMR and fluorescence spectroscopy.Figure optionsDownload as PowerPoint slide
