The title molecule, C22H17F3N2OS, adopts a trans–cis conformation with respect to the positions of the carbonyl and trifluoromethylbenzene groups against the thiocarbonyl group across the C—N bonds. The molecular structure is stabilized by an intramolecular N—H⋯O hydrogen bond with an S(6) ring motif. The trifluoromethyl-substituted benzene ring forms dihedral angles of 66.05 (9) and 47.19 (9)° with the terminal phenyl rings and is twisted from the O=C—N—(C=S)—N carbonylthiourea plane [maximum deviation = 0.0535 (12) Å], making a dihedral angle of 63.59 (8)°. In the crystal, N—H⋯O and C—H⋯F hydrogen bonds link the molecules into a layer parallel to the bc plane. A C—H⋯π interaction is also observed.

An acetone (30 ml) solution of 2-triflouroaniline (1.25 g, 8.4 mmol) was added to a round-bottom flask containing 2,2-diphenylacetyl chloride (1.93 g, 8.4 mmol) and ammonium thiocyanate (0.64 g, 8.4 mmol). The mixture was put at reflux for 1.5 H then filtered off and left to evaporate at room temperature. The colourless precipitate obtained was washed with water and cold ethanol. Colourless crystals suitable for X-ray analysis were obtained by recrystallization of the precipitate in acetone.
N-bound H atoms were located in a difference Fourier map. Atom H1N1 was refined freely [N—H = 0.96 (3) Å], while atom H1N2 was refined with a bond restraint N—H = 0.85 (2) Å [refined distance: N1—H1N1 = 0.807 (15) Å]. The remaining H atoms were positioned geometrically (C—H = 0.95 or 1.00 Å) and refined using a riding model with Uiso(H) = 1.2Ueq(C). In the final
one outlier was omitted (10 0 -7).Data collection: APEX2 (Bruker, 2009); cell

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. |

Recent studies have shown that thiourea derivatives are potential biologically active agents, such as antimicrobials and HIV inhibitors (Vankatachalam et al., 2001). The molecular structure of the title compound is shown in Fig. 1. The bond lengths (Allen et al., 1987) and angles are within normal ranges and are comparable to the related structures (Yusof, Arshad et al., 2012; Yusof, Embong et al., 2012; Yusof, Mutalib et al., 2012). The molecule adopts a trans-cis configuration with respect to the positions of diphenylmethane and trifluoromethylbenzene (F1–F3/C16–C22) groups, respectively, to the sulfur (S1) atom across the C—N bond. The trifluoromethyl-substituted benzene ring (C16–C21) forms dihedral angles of 66.05 (9) and 47.19 (9)° with the terminal phenyl rings, C1–C6 and C8–C13, respectively. Furthermore, the trifluoromethylbenzene plane (C16–C22) is slightly twisted from the carbonyl thiourea moiety (S1/O1/N1/N2/C15/C14) with a C15—N1—C16—C21 torsion angle of 119.3 (2)°. In the molecule, an intramolecular N2—H1N2···O1 hydrogen bond forms an S(6) graph-set motif (Bernstein et al., 1995).
In the crystal (Fig. 2), molecules are linked into a one-dimensional chain along the c-axis via intermolecular N2—H1N2···O1 hydrogen bonds (Table 1) and further connected into a two dimensional layer parallel to the bc-plane by intermolecular C9—H9A···F1 hydrogen bonds (Table 1). In addition, a C7—H7A···Cg1 (Table 1) interaction is also observed in the crystal structure (Cg1 is the centroid of C1–C6).
