In the mol-ecule of the title compound, C(15)H(11)NO(4), the essentially planar phthalide group is oriented at a dihedral angle of 56.78 (5)° with respect to the substituted aromatic ring. An intra-molecular N-H⋯O hydrogen bond results in the formation of a non-planar six-membered ring, which adopts a nearly flattened-boat conformation. In the crystal structure, inter-molecular C-H⋯O, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules, generating centrosymmetric R(2) (2)(8) and R(2) (2)(11) ring motifs and forming a three-dimensional network.
在标题化合物C(15)H(11)NO(4)的分子中，基本呈平面状的邻苯二甲酰基相对于取代的芳香环以56.78 (5)°的二面角取向。分子内的N-H⋯O氢键导致形成一个非平面的六元环，该六元环呈近乎扁平的船式构象。在晶体结构中，分子间的C-H⋯O、O-H⋯O和N-H⋯O氢键连接分子，生成中心对称的R(2) (2)(8)和R(2) (2)(11)环基序，并形成三维网络。
