The title compound, C(14)H(13)ClN(2)O(3)S, features an intra-molecular O-H⋯N hydrogen bond which generates an S(6) ring motif. Inter-molecular N-H⋯O hydrogen bonds and C-H⋯O close contacts link neighbouring mol-ecules forming R(2) (2)(13) ring motifs. In the crystal structure, mol-ecules are further linked by C-H⋯Cl inter-actions, forming one-dimensional extended chains along the c axis. The dihedral angle between the two benzene rings is 86.06 (3)°. The crystal structure is further stabilized by weak inter-molecular π-π inter-actions [inter-planar stacking distance = 3.357 (7) Å].
标题化合物C(14)H(13)ClN(2)O(3)S具有分子内O-H⋯N氢键，形成了S(6)环模式。分子间的N-H⋯O氢键和C-H⋯O紧密接触将相邻分子连接起来，形成R(2) (2)(13)环模式。在晶体结构中，分子通过C-H⋯Cl相互作用进一步连接，沿c轴形成一维延伸链。两个苯环之间的二面角为86.06 (3)°。晶体结构通过弱分子间π-π相互作用[平面间堆积距离 = 3.357 (7) Å]进一步稳定。
