abstract: In the title compound, C(14)H(12)O(3), the phenyl and benzene rings make a dihedral angle of 47.51 (4)°. In the crystal, mol-ecules are dimerized by double O-H⋯O hydrogen bonds, forming centrosymmetric R(2) (2)(8) ring motifs. The dimers are inter-linked by C-H⋯π inter-actions into zigzag layers.
