The title compound, C10H10BrClN2OS, adopts a trans–cis conformation with respect to the position of the 3-chloropropanoyl and 4-bromophenyl groups, respectively, against the thiono C=S bond across their C—N bonds. The benzene ring makes a dihedral angle of 9.55 (16)° with the N2CS thiourea moiety. Intramolecular N—H⋯O and C—H⋯S hydrogen bonds occur. In the crystal, molecules are linked into chains along the c-axis direction by N—H⋯S, C—H⋯S and C—H⋯O hydrogen bonds.

An acetone solution (30 mL) of 4-bromoaniline (0.01 mol, 1.72 g) was added dropwise into a two-necked round-bottomed flask containing 3-chloropropanoylisothiocyanate (0.01 mol). The mixture was refluxed for about 4 h, filtered into a beaker and left to evaporate at room temperature. The filtrate gave colourless crystals after 5 days on slow evaporation of the solvent (yield 79%).
The C based H atoms were positioned geometrically with C–H = 0.93-0.97 Å and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C). The amino H atoms ware located in difference Fourier map and refined freely with using SHELXL instruction 'DFIX 0.87 0.01'.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

The title compound is analogous to the previously reported N-(3-chloropropanoyl)-N'-phenylthiourea (Othman et al., 2010) except the bromine atom is at position-4 of the phenyl ring (Fig. 1). The molecule has trans-cis configuration with respect to the position of the 3-chloropropanoyl and 4-bromophenyl groups, respectively, against the thiono C═S bond across their C4–N1 and C4–N2 bonds. The whole molecule is not planar. The (S1/N1/N2/C2/C3/C4) thiourea moiety and the benzene ring (C5-C10) are planar with maximum deviation of 0.036 (4) Å for C3 atom from the least square plane of the thiourea moiety. The benzene ring makes dihedral angle with the thiourea moiety of 9.55 (16)°, very big reduction compared to the analog, N-(3-chloropropanoyl)-N'-phenylthiourea of 82.62 (10)°. The bond lengths and angles are in normal ranges (Allen et al., 1987). There are N2–H2···O1 and C6–H6···S1 intramolecular hydrogen bonds. In the crystal packing, the molecules are linked by N1–H1···S1i, C2–H2B···S1i and C9–H9···O1ii intermolecular hydrogen bonds form one-dimensional chains along the c axis (Fig. 2).
