The title compound, C 13 H 9 NO 5 , crystallizes in space group P , with Z ′ = 3. The molecules are linked by O—H⋯O hydrogen bonds [H⋯O = 1.79–1.81 Å, O⋯O = 2.625 (3)–2.648 (3) Å and O—H⋯O = 172–176°] into two types of (8) dimer, only one of which is centrosymmetric. An extensive series of soft hydrogen bonds, of C—H⋯O and C—H⋯π(arene) types, links the dimers into a three‐dimensional framework.
