【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,which was in the triclinic system with 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,α=87.361°,β=88.838°,γ=72.414°,V=1.3803?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.更多还原
