摘　　要：A new coordination polymer, [Ag（3,3-pybz）（3,3-Hpybz）]n （1, 3,3-Hpybz = 3-pyri- din-3-yl-benzoic acid）, has been synthesized and characterized by elemental analysis, IR spectra, PXRD, and single-crystal X-ray diffraction. In complex 1, the Ag（1）ions are linked by the paired 3,3-pybz ligands to generate an infinite 1D loop chain, and further through π-π stacking interactions to form a 2D supramolecular architecture. Crystal data for 1： triclinic, space group P1, a = 10.2635（17）, b = 10.3041（12）, c = 10.8060（13） A, V= 1679.1（5）A3, α = 62.028（11）, β = 80.325（15）, γ = 78.738（14）°, Z = 2, C24H17AgN2O4, Mr = 505.27, Dc= 1.698 g/cm3, μ= 1.058 mm--, F（000） = 506, S = 1.012 and T = 293（2） K. The final R = 0.0293 and wR = 0.0667 for 3435 observed reflections with I〉 2a（/）, and R = 0.0350 and wR = 0.0688 for all data.A new coordination polymer, [Ag（3,3-pybz）（3,3-Hpybz）]n （1, 3,3-Hpybz = 3-pyri- din-3-yl-benzoic acid）, has been synthesized and characterized by elemental analysis, IR spectra, PXRD, and single-crystal X-ray diffraction.
