Tetrakis(μ-2-phenylquinoline-4-carboxylato-κ2O:O′)bis[(methanol-κO)copper(II)]

Abstract

The title complex, [Cu2(C16H10NO2)4(CH3OH)2], consists of centrosymmetric wheel-shaped dinuclear neutral molecules in which each CuII atom is coordinated in a slightly distorted square-pyramidal geometry by four O atoms of carboxylate groups from different ligands at the basal plane and an O atom of a methanol molecule at the axial position. In the crystal, the dinuclear complex molecules are linked into one-dimensional supramolecular columns parallel to the b axis by O—H...N hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 3.7259 (11) Å].
