(Received 11 June 2012; accepted 15 June 2012; online 23 June 2012)

The asymmetric unit of the title compound, C11H10N6O3S, contains two independent mol­ecules, each of which is stabilized by an intra­molecular N—H⋯O hydrogen bond, forming an S(6) ring motif. In one mol­ecule, the pyrazole ring forms a dihedral angle of 10.93 (14)° with the benzene ring. The corresponding dihedral angle in the other mol­ecule is 7.03 (14)°. In the crystal, mol­ecules are linked via pairs of (N,N)—H⋯O bifurcated acceptor bonds which, together with C—H⋯O hydrogen bonds, form sheets parallel to (001).

Comment top

The pyrazole ring is a prominent structural moiety found in numerous pharmaceutically active compounds. This is mainly due to the easy preparation and the important pharmacological activity. Therefore, the synthesis and selective functionalization of pyrazoles have been the focus of active research over the years (Isloor et al., 2009). Pyrazoles have been reported to possess antibacterial activity (Rai et al., 2008), and inhibitor activity against DNA gyrase and topoisomerase IV at their respective ATP-binding sites (Bradbury & Pucci, 2008). Moreover, pyrazole-containing compounds have received considerable attention owing to their diverse chemotherapeutic potentials including versatile anti-inflammatory and antimicrobial activities (Girisha et al., 2010). The synthetic route followed for obtaining the title compound involves the diazotization of substituted anilines to give the diazonium salts followed by coupling with ethyl acetoacetate in the presence of sodium acetate to give the corresponding oxobutanoate which on further reaction with thiosemicarbazide in acetic acid gave the required thioamides.

The asymmetric unit contains two independent molecules (Fig. 1), A and B. Each molecule is stabilized by an intramolecular N–H···O hydrogen bond (Table 1), forming a S(6) ring motif (Bernstein et al., 1995). In molecule A, the pyrazole ring (N2A/N3A/C2A-C4A) forms a dihedral angle of 10.93 (14)° with the benzene ring (C5A-C10A). The corresponding dihedral angle in the molecule B is 7.03 (14)°. Bond lengths (Allen et al., 1987) and angles are within normal ranges.

In the crystal (Fig.2), molecules are linked via pairs of intermolecular N5B–H2N5···O3B, N1A–H1N1···O3B and N5A–H1N5···O3A, N1B–H3N1···O3A bifurcated acceptor bonds (Table 1) which together with C10B–H10B···O2A hydrogen bonds form two-dimensional sheets parallel to (001).

Experimental top

To a solution of ethyl-2-[(4-nitrophenyl)hydrazono]-3-oxobutanoate (0.01 mol) dissolved in glacial acetic acid (20 ml), a solution of thiosemicarbazide (0.02 mol) in glacial acetic acid (25 ml) was added and the mixture was refluxed for 4 h. This was cooled and allowed to stand overnight. The solid product which separated out was filtered and dried. It was then recrystallized from ethanol. Crystals suitable for X-ray analysis were obtained by slow evaporation of a solution of the title compound in a 1:2 mixture of DMF and ethanol.

Refinement top

N-bound H atoms were located in a difference Fourier map and refined freely [N–H = 0.84 (4)- 0.98 (4) Å]. The rest of hydrogen atoms were positioned geometrically and refined using a riding model with C–H = 0.95 or 0.98 Å and Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating-group model was applied for the methyl groups.

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 esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
