| Abstract: | The reaction of AgNO3, 4,4´-bipyridine, and thiophene-2,5-dicarboxylate in acetone and H2O at room temperature produces block-shaped colourless crystals after 15 days. The crystal structure was determined by single-crystal X-ray diffraction, using the triclinic space group P (-1). The unit cell parameters are as follows: a = 0.70456(13) nm, b = 1.1415(2) nm, c = 1.8024(3) nm, a = 87.361(4) º，β = 88.838(4) º，γ = 72.414(3)6º, V = 1.3803(4) nm3, Z = 2. Residual factors based on 9648 reflections （R(int) = 0.0636） are R1 = 0.0462, wR2 = 0.1122. The optical absorption properties of Ag2(bpy)2(H2O)](tdc)•6H2O were determined by UV/Vis/NIR diffuse reflectance spectra, which showed strongest absorption in the UV range (350-320 nm). The CCDC number of the compound is 290518. |
