In the title compound, C15H15NO4S, the dihedral angle between the aromatic rings is 80.81 (1)° and the dihedral angle between the planes defined by the S-N-C=O fragment and the sulfonyl benzene ring is 86.34 (1)°. In the extended structure, dimers related by a crystallographic twofold axis are connected by pairs of both N-H⋯O hydrogen bonds and C-H⋯O inter-actions, which generate R 2 (2)(8) and R 2 (2)(14) loops, respectively. A weak aromatic π-π stacking inter-action is also observed [centroid-centroid separation = 3.7305 (3) Å].
在标题化合物C₁₅H₁₅NO₄S中，芳环之间的二面角为80.81 (1)°，由S-N-C=O片段和磺酰苯环所定义平面之间的二面角为86.34 (1)°。在扩展结构中，由晶体学二重轴相关的二聚体通过N-H⋯O氢键对和C-H⋯O相互作用相连，分别形成R₂²(8)和R₂²(14)环。还观察到一个弱的芳香π-π堆积相互作用[质心-质心间距 = 3.7305 (3) Å]。
