(Received 9 February 2011; accepted 17 February 2011; online 23 February 2011)

The molecule of the title pyrazole derivative, C₁₈H₁₉BrN₄S, is twisted. The central pyrazole ring, which adopts a flattened envelope conformation, is almost coplanar with the 4-bromophenyl ring, whereas it is inclined to the 4-(dimethylamino)phenyl ring making dihedral angles of 1.68 (6) and 85.12 (6)°, respectively. The dihedral angle between the two benzene rings is 86.56 (6)°. The dimethylamino group is slightly twisted from the attached benzene ring [C—C—N—C torsion angles = 8.4 (2) and 8.9 (2)°]. In the crystal, molecules are linked by intermolecular N—H⋯S hydrogen bonds into chains along [2 $[\overline{1}]$ 0]. The crystal is further stabilized by C—H⋯π interactions.

Comment top

The pyrazole moiety is one of the core structures in a number of natural products (Xie et al., 2008). Numerous compounds which contain the pyrazole moiety are known to exhibit a wide range of biological properties such as antihypertensive (Mikhaylichenko et al., 2009), analgesic (Hall et al., 2008), anti-inflammatory (Bekhit et al., 2008), antipyretic (Souza et al., 2002), antimicrobial (Gadakh et al., 2010), hypoglycemic (Cottineau et al., 2002), sedative-hypnotic (Hoepping et al., 2007) and antitumor activities (Park et al., 2005). Our on going research on biological activities of pyrazole derivatives led us to synthesize the title compound by cyclization of the chalcone derivative (Ono et al., 2007) with excess thiosemicarbazide. Herein we report the crystal structure of the title compound.

The molecular structure of the title compound is twisted. The central pyrazole ring adopts a flattened envelope conformation with puckering parameter Q = 0.1775 (11) Å and ϕ = 75.9 (3)° (Cremer & Pople, 1975), with the slightly puckered C9 atom having the maximum deviation of 0.1120 (11) Å. The pyrazole ring is coplanar with the 4-bromophenyl whereas inclined to the 4-dimethylaminophenyl rings with dihedral angles of 1.68 (6) and 85.12 (6)°, respectively. The dihedral angle between the two phenyl rings being 86.56 (6)°. The dimethylamino group is slightly twisted from the attached benzene ring with the torsion angles C16–N3–C13–C14 = 8.9 (2)° and C17–N3–C13–C12 = 8.4 (2)°. The carbothioamide is slightly twisted from the pyrazole ring as indicated by the torsions angles N4–C18–N2–N1 = 5.51 (14)° and S1–C18–N2–N1 = -172.28 (7)°. The bond distances agree with the literature values (Allen et al., 1987) and are comparable to those observed in related structures (Chantrapromma et al., 2009; Suwunwong et al., 2009).

In the crystal structure (Fig. 2), the molecules are linked by intermolecular N—H···S hydrogen bonds (Table 1) into chains along the [2 1 0] direction. The crystal is further stabilized by C—H···π interactions (Table 1).

Experimental top

The title compound was synthesized by dissolving (E)-1-(4-bromophenyl)-3-(4-(dimethylamino)phenyl)prop-2-en-1-one (Ono et al., 2007) (0.33 g, 1.0 mmol) in a solution of KOH (0.06 g, 1.0 mmol) in ethanol (20 ml). An excess thiosemicarbazide (0.14 g, 1.5 mmol) in ethanol (20 ml) was then added, and the reaction mixture was vigorously stirred and refluxed for 7 h. The yellow solid of the title compound obtained after cooling of the reaction mixture was filtered off under vacuum. Pale yellow block-shaped single crystals of the title compound suitable for X-ray structure determination were recrystalized from acetone/ethanol (1:1 v/v) by slow evaporation of the solvent at room temperature after several days. M.p. 481–482 K.

Special details top

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.
