In the title compound, C(15)H(13)NO(4)·H(2)O, the Schiff base exists in a zwitterionic form and a bifurcated intra-molecular N-H⋯(O,O) hydrogen bond generates two S(6) rings. The dihedral angle between the two benzene rings is 25.8 (2)°. The crystal structure is stabilized by inter-molecular O-H⋯O hydrogen bonds.
在标题化合物C₁₅H₁₃NO₄·H₂O中,席夫碱以两性离子形式存在,一个分叉的分子内N-H⋯(O,O)氢键形成两个S(6)环。两个苯环之间的二面角为25.8 (2)°。晶体结构通过分子间O-H⋯O氢键得以稳定。
