Synthesis and Crystal Structure of a New Three-Dimensional Complex Constructed From Thiophene-2,5-Dicarboxylic Acid

A new three-dimensional (3D) coordination polymer has been synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectroscopy, and X-ray diffraction. The X-ray diffraction analysis reveals that the polymer crystallizes in monoclinic system, space group C2/c. Unit cell parameters: a = 25.444(2), b = 5.8508(5), c = 19.0633(17) A, α = 90°, β = 124.1250(10)°, γ = 90°, V = 2349.2(4) A3, Z = 4. The polymer can be specified by the Schlafli symbol (42·64)(42·67·8) as a 3D (4,5)-connected net.
