The title compound, C18H16N4OS2, has been synthesized by the condensation reaction of ethyl 3-oxo-2-(phenyl­hydrazono)­butanoate and (S)-benzyl dithio­carbazate. The pyrazolone structure is stabilized by a strong N—H...O=C intra­molecular hydrogen bond.

Pyrazolones constitute a group of organic compounds that have been extensively studied due to their properties and applications. Since the synthesis of antipyrine (2,3-dimethyl-1-phenyl-5-pyrazolone) by Knorr (Knorr,1884), a great deal of attention has been paid to the properties of these compounds and a series of drugs have been synthesized. For examples anti-inflammatory drugs (Clark & Bookland, 2005), compounds with antifungal compounds (Omotowa & Mesubi, 1997), antitumor (Caruso et al., 2000) and antihyperglycemic (Kees et al., 1996). Although the use of pyrazolones as drugs has warranted significant attention, many more applications have been devised for this group of molecules outside the pharmaceutical field. They have been applied to the solvent extraction of metal ions (Bose et al., 2005), for analytical purposes (Ito et al., 2001), in the preparation of azo colorants (Whitaker, 1995), as ligands in complexes with catalytic activity (Bao et al., 2006) and in the synthesis of rare earth metal complexes with interesting photophysical properties (Shi et al., 2005). In present work, we report the preparation the title compound (I), and its crystal structure.

Determination of its crystal structure (Fig.1), the title compound shows one larger conjugation system in the molecule with eight carbon atoms (C11–C18),four nitrogen atoms (N1–N4) and one oxygen (O1),which is further confirmed by by UV spectroscopy.

In the title compound, the dihedral angle between this conjugation system with plane of C7—S1—C8S2 is 13.1°. The benzene ring (C13–C18) is involved in the conjugation system (Table 1). An intramolecular N—H···O C hydrogen bonds is also present in the crystal structure of (I) (Table 2).

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.
