In the title compound, C(15)H(16)N(2)O(4)S, the S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 118.25 (7)°]. The two aromatic rings make a dihedral angle of 62.67 (10)° with each other. An intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules form centrosymmetric dimers via pairwise N-H⋯O inter-actions, forming an R(2) (2)(8) ring motif, and these dimers are connected by N-H⋯O hydrogen bonds, generating a three-dimensional network. Furthermore, a weak C-H⋯π inter-action helps to reinforce the crystal structure. The O atom in the acetamide group is disordered over two positions with major and minor occupancies of 0.52 (5) and 0.48 (5), respectively.
在标题化合物C₁₅H₁₆N₂O₄S中，S原子具有扭曲的四面体几何构型[最大偏差：O - S - O = 118.25 (7)°]。两个芳环彼此间形成的二面角为62.67 (10)°。分子内N - H⋯O氢键形成S(6)环模式。在晶体中，分子通过成对的N - H⋯O相互作用形成中心对称二聚体，形成R₂²(8)环模式，并且这些二聚体通过N - H⋯O氢键相连，生成三维网络。此外，弱的C - H⋯π相互作用有助于加强晶体结构。乙酰胺基团中的O原子在两个位置上无序，主要占有率和次要占有率分别为0.52 (5)和0.48 (5)。
