(Received 12 September 2011; accepted 16 September 2011; online 30 September 2011)

In the title mol­ecule, C12H13N5O2S, a bifurcated intra­molecular N—H⋯O(O) hydrogen bond forms two S(6) ring motifs. The benzene ring forms a dihedral angle of 14.36 (11)° with the pyrazole ring. In the crystal, pairs of N—H⋯S hydrogen bonds form centrosymmetric dimers, generating R22(8) ring motifs, which stack along the b axis.

Comment top

Pyrazoles are a novel class of heterocyclic compounds possessing a wide variety of application in the agrochemical and pharmaceutical industries. Derivatives of pyrazoles are found to show good antibacterial (Rai et al., 2008), anti-inflammatory, analgesic (Isloor et al., 2009), and anticancer activities. Pyrazolines are well known and important nitrogen-containing five membered heterocyclic compounds. Several pyrazoline derivatives have been found to possess considerable biological activities which stimulated research activities in this field (Girisha et al., 2010). In view of these observations and in continuation of our search for biologically active pyrazole derivatives, we herein report the crystal structure of the title compound.

In the molecular structure (Fig. 1), an intramolecular N1—H1N1···O2 and N5—H2N5···O2 hydrogen bond (Table 1) stabilize the molecular structure and forms two S(6) ring motifs (Bernstein et al., 1995). The mean planes of the benzene ring (C1–C6) and the 4,5-dihydro-1H-pyrazole ring (N3/N4/C7–C9) form a dihedral angle of 14.36 (11)°. Bond lengths (Allen et al., 1987) and angles are within normal range.

The crystal packing is shown in Fig. 2. Molecules are linked by pairs of intermolecular N5—H1N5···S1i hydrogen bonds (Table 1) to form dimers, generating R22(8) ring motifs (Bernstein et al., 1995) and these sets of ring motifs are stacked along the b axis.

Experimental top

To a solution of ethyl 2-[(2-methoxyphenyl)hydrazono]-3-oxobutanoate (0.01 mol) in glacial acetic acid (20 ml), a solution of thiosemicarbazide (0.02 mol) in glacial acetic acid (15 ml) was added and the mixture was refluxed for 4 h. It is cooled and allowed to stand overnight. The solid product that separated out was filtered and dried. It was then recrystallized from ethanol. Crystals suitable for X-ray analysis were obtained from 1:2 mixtures of DMF and ethanol by slow evaporation.

Refinement top

N-bound H atoms was located from the difference map and refined freely, [N–H = 0.85 (3)–0.89 (3) Å]. The remaining H atoms were positioned geometrically [C–H = 0.93 or 0.96 Å] and refined using a riding model with Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating group model was applied to the methyl groups.

Special details top

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.
