Crystal structure of N-(3-benzoyl-4,5,6,7-tetrahydro-1-benzothiophen-2-yl)benzamide

Abstract

In the title compound, C22H19NO2S, the cyclohexene ring adopts a half-chair conformation. The dihedral angles between the plane of the thiophene ring and those of its amide- and carbonyl-bonded benzene rings are 7.1 (1) and 59.0 (2)°, respectively. An intramolecular N—H...O hydrogen bond generates an S(6) ring. In the crystal, very weak aromatic π–π stacking interactions [centroid–centroid separation = 3.9009 (10) Å] are observed.
