Abstract: In the title compound, C18H18ClNO4, the imide group with its two alkyl substituents is approximately perpendicular to the plane of the naphthoquinone ring system [dihedral angle = 78.5 (1)°]. Further, the imide carbonyl groups are oriented in an anti sense. In the crystal, the substituted naphthoquinone rings form [pi]-[pi] stacks in the a-axis direction [perpendicular centroid-centroid distance = 3.209 (2) Å and slippage = 4.401 Å].
