The title molecule, C11H10N2S, is almost planar with normal
bond lengths and angles. The crystal packing is stabilized by CÐH and van der Waals interactions.
Comment
Thiophene-containing compounds are known as materials with potential applications in the ¯avor (Bertramet al., 1993) and pharmaceutical industries (Press, 1991), in conducting polymer design (Bloor, 1995), as well as in non-linear optical materials (Nalwa, 1993). Moreover, thiophene derivatives are often used as intermediates in synthetic chemistry. The chemistry of hydrazones has been intensively investigated in recent years, owing to their coordinating capability, pharma-cological activity, antibacterial and antifungal properties, and their use in analytical chemistry as highly selective extractants (Dominoet al., 1984; Sakamotoet al., 1993; Liet al., 1998).
We report here the crystal structure of the title compound, (I) (Fig. 1), synthesized by a condensation reaction of thio-phene-2-carbaldehyde with phenylhydrazine. All bond lengths (Table 1) and angles in (I) are normal. The molecule is distorted from planarity; the dihedral angles of phenyl and thiophene rings with the plane formed by atoms C1/N1/N2/C7/ C11 are 9.6 (3) and 9.82 (3), respectively. The crystal packing (Fig. 2) is mainly stabilized by van der Waals interactions. However, there is a short C7ÐH7 Cg(Cgis the centroid of the phenyl ring) contact (Table 2), which may be attributed to a CÐH interaction.

Experimental
Compound (I) was prepared according to the method described in the literature by Sarõ & GuÈrkan (2003). A stirred mixture of phenylhydrazine (108 g, 1 mmol) and thiophene-2-carboxaldehyde (112 mg, 1 mmol) in methanolic media was re¯uxed for 6 h. After cooling, the precipitate was ®ltered off and was crystallized from methanol (yield 78%, m.p. 398 K).

Special details
Experimental. Melting points were determined in open capillary tubes on a digital Gallenkamp melting point apparatus and are uncorrected. The IR spectra were recorded for KBr disks with a Mattson 1000 F T—IR spectrometer. 1H-NMR spectra were recorded on a FX 90 Jeol 90 MHz NMR, spectrometer in CDCl3 + DMSO-d6 with TMS as an internal standard. Elemental analyses were done on a LECO-CHNS-938. Starting materials was obtained from Fluka or Aldrich. For (I): IR (KBr) ?: 3325 (N—H), 3100,3087,3082, (aromatic C—H), 1603 (C=N), 1579,1535 (C=C). cm-1. 1H NMR (Aceton-d6) ?: 9.23(s, 1H, NH), 8.03(s, 1H, CH=), 7.48–6.63 (m 8H, Aromatic protons). 13 C NMR (Aceton- d6, TMS, ? p.p.m.): 146.20, 142.40, 133.06, 131.94, 129.87, 126.91, 126.17, 120.13, 113.37. Anal calcd for C11H10N2S: C: 65.35, H: 4.95, N: 13.88, S:15.84%.
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.
