The molecule of the title compound, C 16 H 16 N 2 O 4 , lies on a crystallographically imposed center of symmetry at the midpoint of the C-C bond of the oxamide unit. An intramolecular C-HÁ Á ÁO hydrogen bond forms a six-membered ring, and molecules are linked into ribbons along the a axis by N-HÁ Á
