In the molecules of the title compound, C14H11N3O3S, there is an intra
molecular N-H ... O hydrogen bond [2.635(3) Angstrom] between the amid
e N and benzoyl O atoms which completes a nearly planar six-membered r
ing in the central part of the molecule, The benzene rings of the benz
oyl and nitrophenyl moieties form angles of 30.5 (4) and 35.7(4)degree
s, respectively, with the plane of this hydrogen-bonded ring. In the c
rystal, molecules are connected into infinite zigzag chains by N-H ...
O bonds and these chains are linked across centres of symmetry by wea
k 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).
