Abstract
The title compound, C11H12N2O6, crystallizes with two independent molecules in the asymmetric unit, which differ slightly in conformation. The dihedral angle between the amide O=C—N plane and the attached benzene ring is 19.5 (3)° in one molecule and 23.4 (3)° in the other. In the crystal, the two independent molecules are connected alternately by N—H...O hydrogen bonds, forming a chain along theaaxis.
