In the title compound, C12H12ClF3N2OS, the dihedral angle between the benzene ring and the thiourea fragment is 69.41 (5)°. The thiourea N—H atoms adopt an anti conformation, such that one of them forms an intramolecular N—H⋯O hydrogen bond, generating an S(6) ring. In the crystal, both N—H groups form inversion dimers, one via a pair of N—H⋯S hydrogen bonds and one via a pair of N—H⋯O hydrogen bonds. These lead to R22(8) and R22(12) loops, respectively. Weak C—H⋯Cl, C—H⋯F, C—H⋯S and π–π [centroid–centroid separation = 3.7098 (6)Å and slippage = 1.853 Å] interactions also occur.

An equimolar amount of 2-(trifluoromethyl)aniline (1.14 g, 7.09 mmol) in 20 ml acetone was added drop-wise into a stirring acetone solution (75 ml) containing 4-chlorobutanoylchloride (1.00 g, 7.09 mmol) and ammonium thiocyanate (0.54 g, 7.09 mmol). The mixture was refluxed for 1 h. Then, the solution was filtered-off and left to evaporate at room temperature to yield colourless needles.
N-bound H atoms was located from the difference map and refined freely, [N–H = 0.856 (17) and 0.849 (15) Å]. The remaining H atoms were positioned geometrically [C–H = 0.95 or 0.99 Å] and refined using a riding model with Uiso(H) = 1.2 Ueq(C).
As part of our ongoing studies of thiourea derivatives we now describe the title compound. It is analogous to the previously reported N-(4-chlorobutanoyl)-N'- (2-fluorophenyl)thiourea (Yusof et al., 2011) except the fluoro atom is replaced by trifluoromethyl atom.
In the molecular structure (Fig. 1), the benzene ring (C1–C6) is essentially planar with maximum deviation of 0.011 (1) Å at atom C5. The intramolecular N1—H1N1···O1 hydrogen bond (Table 1) generates S(6) ring motifs (Berstein et al., 1995). The bond lengths and angles are within normal ranges and are comparable to the related structures (Khawar Rauf et al., 2006; Yusof et al., 2007).
The crystal packing is shown in Fig. 2. R12(6), R22(8), R22(12) ring motifs (Berstein et al. 1995) are formed by intermolecular N2—H1N2···S1, N1—H1N1···O1 and C9—H9A···S1 (Table 1) hydrogen bonds, respectively. Intermolecular C2—H2A···Cl1 and C3—H3A···F1 (Table 1) interactions linked the molecules into three-dimensional network. π–π interaction [Cg1···Cg1 (-1 - x, 1 - y, 1 - z) = 3.7098 (6) Å;] are also observed [Cg1: C1–C6].

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'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. |

As part of our ongoing studies of thiourea derivatives we now describe the title compound. It is analogous to the previously reported N-(4-chlorobutanoyl)-N'- (2-fluorophenyl)thiourea (Yusof et al., 2011) except the fluoro atom is replaced by trifluoromethyl atom.
In the molecular structure (Fig. 1), the benzene ring (C1–C6) is essentially planar with maximum deviation of 0.011 (1) Å at atom C5. The intramolecular N1—H1N1···O1 hydrogen bond (Table 1) generates S(6) ring motifs (Berstein et al., 1995). The bond lengths and angles are within normal ranges and are comparable to the related structures (Khawar Rauf et al., 2006; Yusof et al., 2007).
The crystal packing is shown in Fig. 2. R12(6), R22(8), R22(12) ring motifs (Berstein et al. 1995) are formed by intermolecular N2—H1N2···S1, N1—H1N1···O1 and C9—H9A···S1 (Table 1) hydrogen bonds, respectively. Intermolecular C2—H2A···Cl1 and C3—H3A···F1 (Table 1) interactions linked the molecules into three-dimensional network. π–π interaction [Cg1···Cg1 (-1 - x, 1 - y, 1 - z) = 3.7098 (6) Å;] are also observed [Cg1: C1–C6].
