The nitrobenzene unit is almost perpendicular to the attached pyrazoline ring, as indicated by the dihedral angle of 84.61 (8)°. In the crystal structure, intermolecular C—H...N contacts link the molecules into dimers in an antiparallel manner. These dimers are further linked into one-dimensional chains along the b axis via C—H...O contacts. The crystal structure is consolidated by three different intermolecular π–π interactions [range of centroid–centroid distances = 3.5160 (11)–3.6912 (11) Å].

The dihedral angle between the two benzene rings is 9.01 (6)°. An intramolecular N—H...O hydrogen bond involving the benzoate unit generates an S(6) ring motif. In the crystal, the molecules are linked by weak C—H...O interactions into infinite chains along the b axis. These chains are further connected into sheets parallel to the ab plane which are stacked approximately along the c axis. A C—H...π interaction is also observed.

There are weak intramolecular N—H...π interactions which might influence the conformation of the molecule. The compound has a stereogenic center but the space group is centrosymmetic so the molecule exists as a racemate.

The benzene rings are almost orthogonal to each other, forming dihedral angles of 87.40 (6), 88.69 (6), 84.88 (6) and 85.12 (6)degrees in the four molecules. The crystal structure is stabilized by intermolecular N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds, together with C-H center dot center dot center dot pi interactions.

They are of current interest due to their wide spectrum of pharmacological properties. In view of the biological activities of benzo[b]thiophene containing molecules, in this present research work, we propose the synthesis of some new benzo[b]thiophene derivatives such as thiadiazoles, oxadiazoles, pyrazolin & diaryl pyrazoles starting from 3-chlorobenzo[b]thiophene-2-carboxyl

The structures of the newly synthesized compounds are confirmed by analytical, IR, NMR and mass spectral data. The newly synthesized compounds were evaluated for their anti-inflammatory, analgesic and anthelmintic activity. The results indicated that dinitrothiophene derivatives 5 are more active.

The C atom of the meth-oxy group is roughly coplanar with its attached ring [displacement = 0.178 (4) Å]. In the crystal, N-H⋯N hydrogen bonds link the mol-ecules into [010] chains. Weak C-H⋯π inter-actions are also observed.

The structures of newly synthesized compounds were established based on analytical and spectral studies. Further these compounds were evaluated for their antioxidant, antifungal and antibacterial activities. Most of the compounds showed moderate to good activity when compared with standard.
