Tetra-kis(μ-2-phenyl-quinoline-4-carboxyl-ato-κ(2)O:O')bis-[(methanol-κO)copper(II)].

The title complex, [Cu(2)(C(16)H(10)NO(2))(4)(CH(3)OH)(2)], consists of centrosymmetric wheel-shaped dinuclear neutral mol-ecules in which each Cu(II) atom is coordinated in a slightly distorted square-pyramidal geometry by four O atoms of carboxyl-ate groups from different ligands at the basal plane and an O atom of a methanol mol-ecule at the axial position. In the crystal, the dinuclear complex mol-ecules are linked into one-dimensional supra-molecular columns parallel to the b axis by O-H⋯N hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.7259†(11)†à ].
