1-(2-Bromo-phen-yl)-3-(4-chloro-butano-yl)thio-urea.

The asymmetric unit of the title compound, C(11)H(12)BrClN(2)OS, consists of two crystallographically independent mol-ecules. In each mol-ecule, the butano-ylthio-urea unit is nearly planar, with maximum deviations of 0.1292†(19) and 0.3352†(18)†à from the mean plane defined by nine non-H atoms, and is twisted relative to the terminal benzene ring with dihedral angles of 69.26†(7) and 82.41†(7)°. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif in each butano-ylthio-urea unit. In the crystal, N-H⋯O hydrogen bonds link the two independent mol-ecules together, forming an R(2) (2)(12) ring motif. The mol-ecules are further connected into a tape along the c axis via N-H⋯S and C-H⋯S hydrogen bonds.
