N-(3-Chloro-1,4-dioxo-1,4-di­hydro­naph­thalen-2-yl)-N-propionylpropionamide

In the title mol­ecule, 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 naphtho­quinone 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, mol­ecules are connected by weak C—H...O hydrogen bonds, as well as π–π stacking inter­actions [centroid–centroid distance = 3.888 (3) Å], forming a three-dimensional network.
