Abstract: In the title compound, C10H13O4N2+·NO3-, the nitro group and the benzene ring are essentially coplanar. The dihedral angle between the benzene ring and the methylcarboxylate plane is 49.6 (3)°. The crystal structure is stabilized by cation-anion N-H
O and N-H
N hydrogen bonds, building sheets parallel to (001).
