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 P with a = 8.3959(7), b = 11.8088(12), c = 12.8175(13) Å, α = 85.507(2), b = 79.245(1), γ = 84.174(2)^o, V = 1239.7(2) ų, Z = 2, C₂₈H₂₂AgN₃O₈, M_r = 636.36, D_c = 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) ų, Z = 4, C₂₂H₃₀Ag₂N₄O₁₁, M_r = 742.24, D_c = 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 Ag^I. 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.
