The title compound, C 18 H 12 N 2 O 6 , crystallizes with two halfmolecules in the asymmetric unit. All molecules lie on a centre of inversion. The dihedral angles between the central and terminal benzene rings are 74.75 (4) and 85.25 (5) for the two molecules in the asymmetric unit.
In the title compound, C~14~H~12~N~2~O~3~, the dihedral angle between the two aromatic rings is 86.13 (15)°. Intermolecular N—H...O hydrogen bonds [N...O = 2.886 (3) Å and N—H...O = 174 (3)°] between the NH~2~ and C=O groups link the molecules into a one-dimensional ribbon augmented by secondary N—H
The molecule of the title compound, C 14 H 10 N 4 O 6 , lies on a crystallographically imposed center of symmetry at the midpoint of the C-C bond of the oxamide unit. Molecules are linked into zigzag chains by N-HÁ Á ÁO hydrogen bonds. The packing is further stabilized by van der Waals forces.
