Abstract: In the title cooordination polymer, {[Cu(C₆H₂O₄S)(C₁₀H₉N₃)(H₂O)]·C₃H₇NO·H₂O}_n, the Cu^II atom is in a square-pyramidal environment defined by an apically coordinated water molecule, carboxyl O atoms from two different thiophene-2,5-dicarboxylate dianions and the two N atoms of a chelating di-2-pyridylamine ligand. The thiophene-2,5-dicarboxylate dianion functions as a ₂-bridging ligand to form a zigzag polymeric chain. In addition, N-HO and O-HO intermolecular hydrogen bonds link the chains into a three-dimensional network structure.
