The reaction of AgNO3,1,3-bis(4-pyridyl)propane,thiophene-2,5-dicarboxylate in acetone aqueous solution produces block colourless crystals [Ag(bpp)]2(tdc)·8H2O at room temperature. [Ag(bpp)]2(tdc)·8H2O consists of parallel sinusoid-like cationic chains, [Ag(bpp)]∞, interspersed with organic tdc2- anions which play the role of charge compensation in the crystal structure. The lattice water molecules are situated among these chains and stabilized by rich hydrogen-bonding interactions and lattice water molecules may play a role in the orientation of the tdc2- in the crystal packing. The crystal data: monoclinic C2/c, a=3.544 7 nm, b=0.920 03 nm, c=2.411 9 nm,β=106.56°, V=7.546 nm3, Z=8. The residual factors based on 6 563 reflections (Rint=0.056 7) are R1=0.046 3, wR2=0.114 2. OPtical absorption properties and band gaps of title compound were determined with UV/Vis/NIR diffuse reflectance spectra. CCDC: 286751.
