Abstract

The Cu(II) atom in the title complex, [Cu(C14H11O3)Cl(C10H8N2)], exists within a ClN2O2 donor set defined by a chloride ion, an asymmetrically chelating carboxyl­ate ligand, and a symmetrically chelating 2,2′-bipyridine mol­ecule. The coordination geometry is square pyramidal with the axial site occupied by the O atom forming the weaker Cu—O inter­action. The hy­droxy group forms an intra­molecular hydrogen bond with the axial O atom, as well as an inter­molecular O—H⋯Cl hydrogen bond. The latter leads to the formation of [100] supra­molecular chains in the crystal, with the Cu(II) atoms lying in a line.
