There are two independent molecules in the asymmetric unit of the title compound, C15H6Cl2N2O2. The conjugated four-ring system is essentially planar in each molecule [maximum deviation = 0.089 (2) Å]. In the crystal, weak intermolecular C—H...Cl, C—H...O and C—H...·N interactions help to stabilize the packing.
