title: 2-(4-Nitrophenoxy)benzoic acid: a three-dimensional hydrogen-bonded framework in a triclinic structure having Z' = 3.
abstract: The title compound, C(13)H(9)NO(5), crystallizes in space group P-1, with Z' = 3. The molecules are linked by O-H...O hydrogen bonds [H...O = 1.79-1.81 A, O...O = 2.625 (3)-2.648 (3) A and O-H...O = 172-176 degrees ] 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.
