Abstract: In the title compound, C₁₈H₁₈N₂O₄, the molecule has a crystallographically imposed center of symmetry. The dihedral angles between the piperazinedione ring and the two outer aromatic rings are 57.25 (7)°. Molecules of (I) interact via weak intermolecular C-HO interactions, forming ribbons along the b axis.
