title: 2-Chloro-3-(4-chloro-benzamido)-1,4-naphthoquinone.
abstract: The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C(17)H(9)Cl(2)NO(3), while the dihedral angle between the amide group and the 4-chloro-phenyl 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 mol-ecules into chains in the a-axis direction. In addition, these chains are linked by weak inter-molecular C-H⋯O inter-actions.
