title: Crystal structure of N-[3-(2-chloro-benzo-yl)-5-ethyl-thio-phen-2-yl]-2-[(E)-(2-hy-droxy-benzyl-idene)amino]-acetamide.
abstract: In the title compound, C22H19ClN2O3S, the dihedral angle between the mean planes of the thio-phene ring and the chloro-phenyl and hy-droxy-phenyl 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. Intra-molecular O-H⋯N and N-H⋯O hydrogen bonds each generate S(6) ring motifs. In the crystal, weak C-H⋯O inter-actions link the mol-ecules, forming chains along the c axis and zigzag chains along the b axis, generating sheets lying parallel to (100).
