(Received 8 May 2010; accepted 25 June 2010; online 7 July 2010)

In the crystal structure of the title compound, C18H12N2OS, centrosymmetric dimers are stabilized both by van der Waals inter­actions and by two types of inter­molecular O—H⋯N hydrogen bonds. In addition, an intra­molecular C—H⋯S hydrogen bond is observed. The dihedral angles between the central ring and the two pendant phenyl rings are 7.4 (1) and 45.06 (9)°.

Comment top

Oximes can act both as donors and acceptors for hydrogen bonds, making them interesting materials for supramolecular chemistry (Bertolasi et al., 1982; Chertanova et al., 1994). Besides, oximes are among the most useful and versatile intermediates in synthetic organic chemistry, the Beckmann rearrangement and the reduction of oximes being two of the most useful transformations. Oximes are also interesting due to their wide application in medicine, industry and analytical chemistry. Owing to the oxime bond oxime derivatives also posses therapeuthic efficacy as a chemical tool for targeted intracellular delivery of synthetic oligonucleotides via conjugation to cell-penetrating peptides (Rappoport & Liebman, 2008). On the other hand, the discoveries of thiophene compounds in fungi and higher plants has awakened the interest of the natural product chemist in the chemistry of thiophenes (Gronowitz, 1963) Synthesis of thiophen-oximes resulted from our interest in the investigation of reactions between nitro-thiophene derivatives and arylacetonitriles. Due to containing oximic and nitrile moieties the title compound may be useful in prospective modifications. The molecule of the title compound is not planar: the phenyl moiety neighbouring to nitrile group is deviated from planarity by 45.06 (9)° and the second phenyl moiety is twisted by 7.4 (1)°. In the crystal structure solely the anti-isomer of the oxime is observed. The components of the structure are united into a three dimensional network by an extensive system of O—H···N intermolecular hydrogen bonds next to the intramolecular C(1)—H(1)···S(1) hydrogen bond. Adjacent molecules are linked into dimers by intermolecular O—H···N hydrogen bonds under participation of oximic groups. The distance between the nitrile nitrogen and oximic hydrogen atom of another molecule is 2.403 (2) Å. Dimers are further stacked in columns along the unique axis by π-π stacking interactions with centroid-centroid distances of 3.6 (1) Å.

Experimental top

To 40 ml of a methanolic solution of potassium hydroxide (3.36 g, 60 mmoles) phenylacetonitrile (1.17 ml, 10 mmol) was added with stirring. Then 10 ml of a methanolic solution of 2-iodo-5-nitrothiophene (2.55 g, 10 mmol) was added to the reaction mixture. The suspension was stirred at room temperature until precipitation of product was ended. The reaction mixture was then poured into 100 ml of water and acidified by adding acetic acid. The precipitate was isolated by filtration, washed with water and dried. Red (orange) needles of title compound, m.p. (with decomp.) 394–395 K, yield 2.12 g (60%), were obtained after slowly cooling down an ethanolic solution.

Refinement top

Positions of H atoms were calculated and refined using SHELXL constraints. All H atoms, including one bonded to O, were positioned geometrically with O—H = 0.82 Å and with C—H = 0.93 Å. Finally, thermal parameters of all hydrogen atoms were refined using an overall thermal isotropic parameter excluding the hydrogen atom of OH-group. Thermal parameter for hydrogen of OH-group was refined individually.

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.
