1-{2-[(4-Chlorobenzylidene)amino]phenyl}-3-phenylthiourea
Abstract
The asymmetric unit of the title compound, C20H16ClN3S, contains two independent molecules, A and B. In molecule A, the dihedral angles between the central benzene ring and the pendant chlorobenzene and phenyl rings are 6.37 (15) and 64.79 (15)°, respectively. The corresponding values in molecule B are 28.21 (14) and 82.11 (16)°, respectively. Each molecule features an intramolecular N—H...N hydrogen bond, which generates an S(5) ring. In the crystal, molecules A and B form dimers, being linked by two N—H...S hydrogen bonds with graph-set notation R22(8).
