1-benzoyl-3-(4-nitrophenyl)thiourea

In the molecules of the title compound, C14H11N3O3S, there is an intramolecular N-H ... O hydrogen bond [2.635(3) Angstrom] 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)degrees, 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 Angstrom).
