Abstract: The title complex, [Cu₂(C₁₆H₁₀NO₂)₄(H₂O)₂], has a centrosymmetric wheel-shaped dinuclear structure in which two symmetry-related Cu^II centers are bridged by four carboxylate groups of distinct 2-phenylquinoline-4-carboxylate (phqc) ligands, the Cu-Cu separation being 2.6507 (12) Å. Each Cu^II center is five-coordinated by four O atoms of carboxylate groups in the basal plane and one O atom of a water molecule in the apical position. In addition, the dinuclear molecules are linked by intermolecular O-HN hydrogen bonds to form a one-dimensional supramolecular chain.
