Abstract: The two symmetry independent mol-ecules of the title compound, C 19H13Cl2NO4, show similar conformations with the acetyl group twisted strongly relative to the remaining, virtually flat (r.m.s. deviations = 0.0173 and 0.0065 Å), part of the mol-ecule. The hydroxyl groups of the 8-hydroxy-quinoline residues are involved in intra-molecular O - H⋯N hydrogen bonds, which, in one case, forms a part of a three-center inter-action. Inter-molecular O - H⋯O hydrogen bonds assemble the mol-ecules into a one-dimensional polymeric structure extended along the a axis. The 4-hydroxy-phenyl group of one mol-ecule forms an O - H⋯O hydrogen bond, in which the hydroxyl H atom is disordered, with its inversion center counterpart.
