The title compound, C13H9NO5, crystallizes in space group P (1) over bar, with Z'=3. The molecules are linked by O-H...O hydrogen bonds [H...O=1.79-1.81 Angstrom, O...O=2.625 (3) -2.648 (3) Angstrom and O-H...O=172-176degrees] into two types of R-2(2)(8) dimer, only one of which is centrosymmetric. An extensive series of soft hydrogen bonds, of C-H...O and C-H...pi(arene) types, links the dimers into a three-dimensional framework.
