The title compound, C10H12O5N2, crystallizes with two independent mol-ecules in the asymmetric unit. The mol-ecules in the crystal structure are arranged into one-dimensional substructural ribbon motifs stabilized by a combination of two O - H⋯O and three N - H⋯O inter-molecular hydrogen bonds, and also augmented by short C=O⋯C=O carbon-yl-carbonyl inter-actions. Two inter-molecular C - H⋯O short contacts between adjacent ribbons generate complex two-dimensional sheets on the ab plane. Adjacent sheets are linked via C - H⋯π(arene) inter-actions, resulting in a complex three-dimensional framework.
