The title Schiff base compound, C(13)H(11)N(3)O(5)S, exists in an E configuration with respect to the C=N double bond. The benzene rings are almost coplanar, making a dihedral angle of 2.82 (6). The sulfonamide group is twisted away from the attached phenyl ring with an N-S-C-C torsion angle of 64.84 (11)°. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecule, generating an S(6) ring motif. In the crystal, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
席夫碱化合物C(13)H(11)N(3)O(5)S相对于C=N双键呈E构型。苯环几乎共面,二面角为2.82 (6)。磺酰胺基团与相连的苯环扭转,N-S-C-C扭转角为64.84 (11)°。分子内O-H⋯N氢键使分子稳定,形成S(6)环 motif。在晶体中,分子间N-H⋯O和C-H⋯O氢键将分子连接成三维网络。
