(Received 19 June 2013; accepted 1 July 2013; online 10 July 2013)

In the mol­ecule of title pyrazoline derivative, C17H18N4OS, the pyrazole ring adopts an envelope conformation with the flap atom, which bears the meth­oxy­phenyl substituent, displaced by 0.0750 (12) Å from the plane through the other ring atoms. The two substituted benzene rings make a dihedral angle of 70.59 (6)°. The meth­oxy group is twisted slightly with respect to the attached benzene ring [Cmeth­yl—O—C—C torsion angle = −8.84 (15)°]. An intra­molecular N—H⋯N hydrogen bond occurs. In the crystal, the pyrazoline mol­ecules are linked by N—H⋯O and N—H⋯S hydrogen bonds into zigzag layers parallel to the bc plane and stacked along the a axis by ππ inter­actions with centroid–centroid distances of 3.4690 (7) and 3.5792 (7) Å. C—H⋯π inter­actions are also present.

Pyrazolines are five-membered heterocyclic compounds having three carbon atoms and two adjacent nitrogen atoms within the pyrazoline ring. Numerous pyrazolines have been found to possess considerable biological activities with several prominent effects, such as antimicrobial (Sakthinathan et al., 2012), antiamoebic (Husain et al., 2008), anti-inflammatory (Shoman et al., 2009), analgesic (Khode et al., 2009) and anticancer (Lv et al., 2011; Shaharyar et al., 2010) activities, as well as optical properties (Gong et al., 2010). Owing to these interesting properties of pyrazolines and our on-going research on fluorescence and biologically active compounds, the title pyrazoline derivative (I) was synthesized by cyclization of the chalcone derivative with thiosemicarbazide. Herein the crystal structure of (I) is reported.

In the molecule of (I), C17H18N4OS, the pyrazole ring is in an envelope conformation (pucker atom at C9 with deviation of 0.0750 (12) Å) with puckering parameter Q = 0.1186 (12) Å and ϕ = 71.2 (5)° (Cremer & Pople, 1975). The mean plane through pyrazole ring makes the dihedral angles of 5.75 (6) and 73.76 (6)° with 4-aminophenyl and 4-methoxyphenyl rings, respectively, whereas the dihedral angle between the two substituted phenyl rings is 70.59 (6)°. The methoxy group is slightly twisted from its attached benzene ring with the torsion angle C17–O1–C13–C14 = -8.84 (15)°. The carbothioamide unit is also twisted from pyrazole ring as indicated by the torsion angles N21—N2–C16–N4 = 9.07 (15)° and N1–N2–C16–S2 = -171.50 (8)°. An intramolecular N4—H2N4···N1 hydrogen bond generates an S(5) ring motif (Fig. 1; Bernstein et al., 1995). Bond distances in (I) are in normal ranges (Allen et al., 1987) and comparable with those observed in related structures (Fun et al., 2011; Quah et al., 2013).

In the crystal packing (Fig. 2), the molecules are linked in a zigzag fashion by Namino—H···S and Nthioamide—H···O intermolcular interactions (Table 1) into a two dimensional network parallel to the bc plane which further stacks along the a-axis by π···π interactions with centroid..centroid distances of Cg1···Cg2ii = 3.5792 (7) Å and Cg2···Cg2v = 3.4690 (7) Å [symmetry code (v) = -x, 2 - y, -z and Cg1 is the centroid of N1/N2/C7–C9 ring]. C—H···π interactions (Table 1) are also present.

Experimental top

The title compound was synthesized by dissolving (E)-1-(4-aminophenyl)-3-(4-methoxyphenyl)prop-2-en-1-one (0.25 g, 1.0 mmol) in a solution of KOH (0.11 g, 2.0 mmol) in ethanol (20 ml). An excess thiosemicarbazide (0.18 g, 2.0 mmol) in ethanol (20 ml) was then added, and the reaction mixture was vigorously stirred and refluxed for 4 h. The brown solid of the title compound obtained after cooling was filtered off under vacuum. Brown block-shaped single crystals of the title compound suitable for X-ray structure determination were recrystallized from C2H5OH by slow evaporation of the solvent at room temperature after several days. M. p. 479–480 K.

Refinement top

Amino and thioamide H atoms were located in a difference Fourier map and refined isotropically. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(C—H) = 0.95 Å for aromatic, 1.00 Å for CH, 0.99 Å for CH2 and 0.98 for CH3 atoms. The Uiso values were constrained to be 1.5Ueq of the carrier atom for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl group.

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.
