Abstract: The title compound, [Cu₂(C₁₁H₈NO₃)₂Cl₂], 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 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 - stacking interactions, with interplanar distances of 3.549 (5) and 3.763 (5) Å, thereby forming a two-dimensional planar network perpendicular to the ab plane. Furthermore, a weak interaction [2.750 (4) Å] 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.
