文摘

The reactions of triphenylphosphine (PPh₃) and 4,4¡ä-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(¦Ì-bipy)]₂(BF₄)₂}_n (3) and {[Ag(PPh₃)₂(CH₃CN)]₂(¦Ì-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.
