N-(2-Chloro­phenyl)-2-{(1E)-[4-(dimethyl­amino)phenyl]methyl­eneamino}-4,7-dihydro-1-benzothio­phene-3-carboxamide

In the title compound, C₂₄H₂₂ClN₃OS, variations in C—N bond lengths and angles around the N atoms indicate delocalization of the N-atom lone pair. The benzothio­phene moiety is essentially planar. The dimethyl­amino­phenyl and o-chloro­benzene rings form dihedral angles of 41.9 (1) and 26.2 (2)°, respectively, with the benzothio­phene plane. The molecular structure is stabilized by N—H...Cl, N—H...N, C—H...N, C—H...S and C—H...O hydrogen bonds. Mol­ecules pack as layers parallel to (101).

2-Acetamido-N-(2-chloro­phenyl)-4,5,6,7-tetrahydro­benzothio­phene-3-carboxamide

In the title compound, C₁₇H₁₇ClN₂O₂S, the o-chloro­phenyl group is almost coplanar with the thio­phene ring and the C—N bond distance indicates delocalization of π bonding across the ring systems. There are intramolecular N—H...O, N—H...Cl and C—H...O hydrogen bonds, and intermolecular C—H...O interactions.
