摘 要: | The title complexes(NH4)Ag(dpe)(H2bptc)](1) and Ag2(bpy)(ox)·7H2O(2) were synthesized via slow evaporation at room temperature,and characterized by elemental analysis and infrared spectra.The crystal of 1 crystallizes in triclinic,space group P1 with a = 8.3959(7),b = 11.8088(12),c = 12.8175(13) ,α = 85.507(2),β = 79.245(1),γ = 84.174(2)o,V = 1239.7(2) 3,Z = 2,C28H22AgN3O8,Mr = 636.36,Dc = 1.705 g/cm3,F(000) = 644 and μ(MoKα) = 0.874 mm-1.The final R = 0.0479 and wR = 0.1426 for 3632 observed reflections with I > 2σ(I) and R = 0.0559 and wR = 0.1503 for all data.The crystal of 2 crystallizes in orthorhombic,space group Pnna with a = 17.2291(17),b = 7.5289(6),c = 21.369(2),V = 2771.9(4) 3,Z = 4,C22H30Ag2N4O11,Mr = 742.24,Dc = 1.779 g/cm3,F(000) = 1488 and μ(MoKα) = 1.476 mm-1.The final R = 0.0648 and wR = 0.2058 for 1996 observed reflections with I > 2σ(I) and R = 0.0769 and wR = 0.2192 for all data.X-ray diffraction reveals that in complexes 1 and 2,both 1,2-di(4-pyridyl)ethylene and 4,4'-bipyridine act as typical bidentate N-donor ligands to link two Ag centers.3,3'4,4'-Biphenyltetracarboxylate and oxalate anions play the role of organic linkers and counter-ions to balance the cationic charge of AgI.The rich hydrogen-bonding interactions and ligand-unsupported Ag…Ag interactions as well as π-π stacking interactions contribute to the construction of three-dimensional sandwich-like frameworks.
