Crystal structure of N-[3-(2-chlorobenzoyl)-5-ethylthiophen-2-yl]-2-[(E)-(2-hydroxybenzylidene)amino]acetamide

Abstract

In the title compound, C22H19ClN2O3S, the dihedral angle between the mean planes of the thiophene ring and the chlorophenyl and hydroxyphenyl rings are 70.1 (1) and 40.2 (4)°, respectively. The benzene rings are twisted with respect to each other by 88.9 (3)°. The imine bond lies in an E conformation. Intramolecular O - N and N - O hydrogen bonds each generate S(6) ring motifs. In the crystal, weak C - O interactions link the molecules, forming chains along the c axis and zigzag chains along the b axis, generating sheets lying parallel to (100).
