N-(4-Chloro-butano-yl)-N'-phenyl-thio-urea.

The asymmetric unit of the title compound, C(11)H(13)ClN(2)OS, contains two independent mol-ecules. Both mol-ecules maintain a trans-cis configuration with respect to the position of the carbonyl group and the benzene ring against the thione group across the C-N bonds. The mol-ecules are stabilized by intra-molecular N-H⋯O hydrogen bonds. In the crystal, the mol-ecules are linked by inter-molecular N-H⋯S, N-H⋯O and C-H⋯S hydrogen bonds into chains along the c axis. C-H⋯π inter-actions further stabilize the crystal structure.
