title: 2-(2-Nitro-anilino)-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[b]thio-phene-3-carbonitrile.
abstract: The title compound, C(16)H(15)N(3)O(2)S, was synthesized by the reaction of 2-amino-5,6,7,8-tetra-hydro-4H-cyclo-hepta-[b]thio-phene-3-carbonitrile and o-fluoro-nitro-benzene. The thio-phene and nitro-phenyl rings and amino and carbonitrile groups are coplanar with a maximum deviation of 0.046 (2) Å and a dihedral angle of 0.92 (6)° between the rings. The cyclo-hepta ring adopts a chair conformation. Intra-molecular N-H⋯O and C-H⋯S inter-actions occur. In the crystal, the mol-ecules form layers that are linked by π-π stacking inter-actions between the thio-phene and benzene rings [centroid-centroid distances = 3.7089 (12) and 3.6170 (12) Å].
