2-Chloro-3-(4-chloro-benzamido)-1,4-naphthoquinone.

The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C17H9Cl2NO3, while the dihedral angle between the amide group and the 4-chloro­phenyl ring is 21.9 (2)°. The conformation of the N—H and C=O bonds are anti to each other. N—H⋯Cl hydrogen bonds link the mol­ecules into chains in the a-axis direction. In addition, these chains are linked by weak inter­molecular C—H⋯O inter­actions.
