Abstract: The crystal structure of the title compound, [Cu₂Cl₄(C₉H₇NO)₂], has been determined from powder diffraction data. The crystals are built of dinuclear complex molecules, with a central four-membered Cu₂O₂ ring located about a crystallographic inversion centre, which involves two Cu atoms, each carrying two terminal chloro ligands each [Cu-Cl = 2.213  (8) and 2.222  (8)  Å] and two O atoms of the quinoline N-oxide ligand. The Cu atom has a square-planar coordination, with considerable distortions due to the four-membered ring [O-Cu-O = 78  (1)° and Cl-Cu-Cl = 100.2  (3)°].
