In the crystal structure of the title compound, C(14)H(12)O(4), the mol-ecules form classical O-H⋯O hydrogen-bonded carb-oxy-lic acid dimers. These dimers are linked by C-H⋯pi; inter-actions into a three-dimensional network. The benzene rings are oriented at a dihedral angle of 69.6 (3)°.
在标题化合物C(14)H(12)O(4)的晶体结构中,分子形成经典的O-H⋯O氢键连接的羧酸二聚体。这些二聚体通过C-H⋯π相互作用连接成三维网络。苯环以69.6 (3)°的二面角取向。
