{2-[(4-nitrobenzylidene)amino]-4,5,6,7-tetrahydro-1-benzothiophen-3-yl} -(phenyl)methanone

Abstract

In the title compound, C22H18N2O 3S, disorder is found in the benzoyl group (A and B), as well as for four C atoms of the cyclohexene ring. Two orientations were modeled in a 0.583 (5):0.417 (5) ratio. The cyclohexene ring is in a distorted chair conformation. The dihedral angles between the mean plane of the thiophene ring and the 4-nitrobenzene and phenyl rings are 30.9 (8) and 64.8 (3) (A) and 62.4 (7)° (B). The mean planes of the 4-nitrobenzene and the phenyl rings are almost perpendicular to each other, with dihedral angles of 85.4 (1) (A) and 83.9 (8)° (B). An extensive array of weak C-H⋯O interactions consolidate molecules into a three-dimensional architecture, forming chains along [001] and [010] and layers parallel to (011).
