In the title compound, C(12)H(9)ClN(2)O(4)S, the N-H bond in the -SO(2)-NH- segment is syn to both the ortho-nitro group in the sulfonyl-benzene ring and the ortho-Cl atom in the aniline ring. The mol-ecule is twisted at the S-N bond with a torsion angle of 75.0 (2)°. The dihedral angle between the sulfonyl-benzene and aniline rings is 54.97 (11)°. The amide H atom shows bifurcated hydrogen bonding, generating S(7) and C(4) motifs. In the crystal, N-H⋯O(S) hydrogen bonds link the mol-ecules into chains.
在标题化合物C₁₂H₉ClN₂O₄S中，-SO₂-NH-片段中的N-H键与磺酰苯环上的邻硝基以及苯胺环上的邻氯原子均呈顺式。分子在S-N键处发生扭曲，扭转角为75.0 (2)°。磺酰苯环与苯胺环之间的二面角为54.97 (11)°。酰胺H原子呈现出分叉氢键，形成S(7)和C(4) motif。在晶体中，N-H⋯O(S)氢键将分子连接成链。
