In the molecules of the title compound, C₁₄H₁₁N₃O₃S, there is an intramolecular N-H...O hydrogen bond [2.635 (3) A] between the amide N and benzoyl O atoms which completes a nearly planar six-membered ring in the central part of the molecule. The benzene rings of the benzoyl and nitrophenyl moieties form angles of 30.5 (4) and 35.7 (4)°, respectively, with the plane of this hydrogen-bonded ring. In the crystal, molecules are connected into infinite zigzag chains by N-H...O bonds and these chains are linked across centres of symmetry by weak N-H...S interactions, thus forming a two-dimensional network. Van der Waals interactions between layers lead to a crystal structure with one very short axis (4 A).
