There are two independent molecules in the asymmetric unit of the title compound, C15H6C12N2O2. The conjugated four-ring system is essentially planar in each mol-ecule [maximum deviation = 0.089 (2) Å]. In the crystal, weak inter-molecular C - H⋯Cl, C - H⋯O and C - H⋯·N inter-actions help to stabilize the packing.
