Di-μ-chlorido-bis{[2-(8-quinolyloxy)-acetato-κ3N,O1,O2]copper(II)}

The title compound, [Cu-2(C11H8NO3)(2)Cl-2], is a bicopper(II) complex. Each Cu-II ion is five-coordinated by two O atoms and one N atom from the (8-quinolyloxy) acetate ligand, and by two mu(2)-chloride ligands, thus exhibiting a distorted square-pyramidal CuCl2NO2 coordination environment. Each (8-quinolyloxy) acetate anion acts as a tridentate chelating ligand. In the crystal structure, adjacent quinolyl rings are involved in strong pi-pi stacking interactions, with interplanar distances of 3.549 (5) and 3.763 (5) angstrom, thereby forming a two-dimensional planar network perpendicular to the ab plane. Furthermore, a weak interaction [2.750 (4) angstrom] is observed within these planes between one Cu-II ion and a carboxylate O atom from a ligand in an adjacent molecule, which also contributes to the stability of the structure.
