Abstract: In the title compound, C18H14N2O4, the piperazine ring adopts a chair conformation and the dihedral angle between the aromatic rings is 13.09 (9)°. In the crystal, molecules are linked along the c axis by C-H and N [H(N)-centroid distances = 2.8030 (2) and 3.376 (2) Å] interactions between neighbouring molecules.
