摘　　要：The title compound, a novel Ag（Ⅰ） carboxyarylphosphonate [Ag（H2BCP）（4,4＇- bipy）]·2H2O （H3BCP = p-H2O3PCH2C6H4COOH, 4,4＇-bipy = 4,4＇-bipyridine）, was synthesized by a hydrothermal reaction and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction. It belongs to monoclinic system, space group P21/c with a = 5.7038（11）, b = 22.397（4）, c = 5.602（4） , β = 106.26（3）°, V = 1913.4（7） 3, Z = 4, C18H20N2O7PAg, Mr = 515.20, Dc = 1.788 g/cm3, μ = 1.182 mm–1, F（000） = 1040, the final R = 0.0404 and wR = 0.1216 for 4178 observed reflections with I 2σ（Ⅰ）. In the structure, the Ag（Ⅰ） cations are bridged by 4,4＇-bipy to give rise to 1D chains running along the b axis. These chains are linked further by the interactions of O （from BCP ligands） and Ag atoms to yield 2D layers. Hydrogen bonding interactions and weak π-π stacking interactions between 4,4＇-bipy rings assemble such adjacent layers to generate a 3D supramolecular architecture.The title compound, a novel Ag（Ⅰ） carboxyarylphosphonate [Ag（H2BCP）（4,4＇- bipy）]·2H2O （H3BCP = p-H2O3PCH2C6H4COOH, 4,4＇-bipy = 4,4＇-bipyridine）, was synthesized by a hydrothermal reaction and characterized by elemental analysis, IR spectra and single-crystal X-ray diffraction.
