Abstract: The title compound, catena-poly[[copper(II)--2-{[(E)-(5-formyl-2-oxidophenyl)methylidene]amino}-1-ethanesulfonato(2-)] monohydrate], {[Cu(L)(H₂O)]·H₂O}_n, where H₂L = 2-{[(E)-(5-formyl-2-hydroxyphenyl)methylidene]amino}-1-ethanesulfonic acid (C₁₀H₁₁NO₅S), was synthesized in water-methanol solution and the crystal structure determined by X-ray diffraction analysis. The Cu atom is five-coordinate, forming a distorted square-pyramidal geometry. This geometry includes a weak bond between the Cu atom and the O atom of the formyl group of another ligand, giving a one-dimensional infinite chain structure. The structure is further stabilized by intermolecular hydrogen bonds.
