In the title mol-ecule, C16H14ClNO4, the four essentially planar atoms of the imide group [r.m.s. deviation = 0.0286 (11) Å] form a dihedral angle of 77.36 (13)° with the naphtho-quinone group [maximun deviation = 0.111 (2) Å for the carbonyl O atom in the naphthalene 1-position] and the two imide carbonyl groups are oriented anti with respect to each other. In the crystal, mol-ecules are connected by weak C-H⋯O hydrogen bonds, as well as π-π stacking inter-actions [centroid-centroid distance = 3.888 (3) Å], forming a three-dimensional network.
