title: 1-{2-[(4-Chloro-benzyl-idene)amino]phen-yl}-3-phenyl-thio-urea.
abstract: The asymmetric unit of the title compound, C(20)H(16)ClN(3)S, contains two independent mol-ecules, A and B. In mol-ecule A, the dihedral angles between the central benzene ring and the pendant chloro-benzene and phenyl rings are 6.37 (15) and 64.79 (15)°, respectively. The corresponding values in mol-ecule B are 28.21 (14) and 82.11 (16)°, respectively. Each mol-ecule features an intra-molecular N-H⋯N hydrogen bond, which generates an S(5) ring. In the crystal, mol-ecules A and B form dimers, being linked by two N-H⋯S hydrogen bonds with graph-set notation R(2) (2)(8).
