In the title compound, C14H12ClNO4S, the dihedral angle between the aromatic rings is 82.07 (1)° and the dihedral angle between the planes defined by the S-N-C=O fragment and the sulfonyl benzene ring is 82.46 (3)°. In the crystal, the mol-ecules are linked into C(4) chains running along [001] by strong N-H⋯O hydrogen bonds. A C-H⋯O intera-ction reinforces the [001] chains: its graph-set symbol is C(7). The chains are cross-linked into (100) sheets by further C-H⋯O inter-actions as C(6) chains along [001]. The structure also features weak π-π stacking inter-actions [centroid-centroid distances = 3.577 (1) and 3.8016 (1) Å].
在标题化合物C₁₄H₁₂ClNO₄S中，芳环之间的二面角为82.07 (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82.46 (3)°。在晶体中，分子通过强N-H⋯O氢键连接成沿[001]方向延伸的C(4)链。一个C-H⋯O相互作用加强了[001]链：其图形集符号为C(7)。这些链通过沿[001]方向作为C(6)链的进一步C-H⋯O相互作用交联成(100)片层。该结构还具有弱的π-π堆积相互作用[质心-质心距离 = 3.577 (1) 和3.8016 (1) Å]。
