2-(2-Nitro-anilino)-4,5,6,7-tetra-hydro-benzo[b]thio-phene-3-carbonitrile.

The title compound, C(15)H(13)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 dihedral angle between the thio-phene and nitro-phenyl rings is 75.15†(2)°. In the crystal, inter-molecular N-H⋯N and C-H⋯O inter-actions lead to the formation of a supra-molecular chain extending along the c-axis direction.
