The title Schiff base compound, C15H17N3O2S, is non-planar with a dihedral angle of 69.88 (4)° between the planes of the benzene rings. In the crystal, pairs of N-H⋯N hydrogen bonds, between the sulfonamide nitro-gen-H atom and the azomethine N atom, link the mol-ecules into inversion dimers, forming R 2 (2)(16) ring motifs. These dimers are linked by N-H⋯O hydrogen bonds, between the sulfonamide nitro-gen-H atom and one sulfonamide O atom, forming sheets lying parallel to (100). Within the sheets there are weak parallel slipped π-π inter-actions involving inversion-related benzene-sulfonamide rings [centroid-centroid distance = 3.8800 (9) Å; normal distance = 3.4796 (6) Å; slippage = 1.717 Å].
席夫碱化合物C15H17N3O2S呈非平面结构，苯环平面之间的二面角为69.88 (4)°。在晶体中，磺酰胺氮-H原子与偶氮甲碱N原子之间的N-H⋯N氢键对将分子连接成反演二聚体，形成R 2 (2)(16)环基序。这些二聚体通过磺酰胺氮-H原子与一个磺酰胺O原子之间的N-H⋯O氢键相连，形成平行于(100)的片层。在片层内，存在涉及反演相关苯-磺酰胺环的弱平行滑移π-π相互作用[质心-质心距离 = 3.8800 (9) Å；垂直距离 = 3.4796 (6) Å；滑移 = 1.717 Å]。
