Abstract: The title compound, [Cu(C₈H₄O₄)(C₅H₅N)₂(H₂O)]_n·0.25nH₂O, was obtained unintentionally as the product of an attempted synthesis of a 4-cyanobenzoate-bridged network complex of copper(II) using pyridine as a base to deprotonate the organic acid. Its crystal structure is built up by one-dimensional helical chains along the c direction and uncoordinated water molecules through intermolecular O-HO hydrogen bonds and van der Waals interactions. The investigated crystal was a partial inversion twin.
