چکیده
In the title compound, C11H7N3S, the thio-phene and pyridine rings are coplanar, forming a dihedral angle of 3.89 (7)°. The conformation about the C=N bond [1.2795 (18) Å] is E. In the crystal, translationally related mol-ecules along the a axis form weak π-π inter-actions [centroid-centroid distance = 3.8451 (8) Å] between the thio-phene rings.

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 dir...
