In the title compound, C15H14O2S, the dihedral angle between the aromatic rings is 8.46 –(8)°. The central enone group is planar (r.m.s. deviation = 0.0267 Å) and is oriented at a dihedral angle of 1.20 (9)° with respect to the benzene ring and at 8.27 (9)° with respect to the thio­phene group. In the crystal, the mol­ecules are linked into polymeric chains extending along the b axis due to inter­molecular O—H⋯O hydrogen bonding. An S(6) ring motif is formed due to a short intra­molecular C—H⋯O contact. C—H⋯π inter­actions involving a methyl group of the 2,5-dimethyl­thienyl group and the benzene ring are present. π–π inter­actions between the centroids of the benzene and heterocyclic rings [3.7691 (9) Å] also occur.

Comment top

An enone system between two aromatic rings is generally known as a chalcones. It is an important class of natural products which serve as precursors for the preparation of various flavonoids and exhibit interesting pharmacological activities (Mojzis et al., 2008). Natural and synthetic chalcones have shown broad spectrum of biological activities such as anti-inflammatory (Vogel et al., 2010), antituberculosis (Hans et al., 2010), antifungal (Bandgar & Gawande, 2010), antimalarial (Domínguez et al., 2001) and antileish-manicidal (Kayser & Kiderlen 2001). Due to wide application of chalcons in the present communication, we report the synthesis and crystal structure of title compound I (Fig. 1).

Recently we have reported the crystal structures of (II) i.e. (E)-1-(2,5-dimethyl-3-thienyl)-3-(2,4,5-trimethoxyphenyl)prop-2-en-1-one (Asiri et al., 2010a) and (III) i.e. (2E)-3-(3,4-dimethoxyphenyl)-1-(2,5-dimethylthiophen-3-yl)prop-2-en-1-one (Asiri et al., 2010b) which are related to the title compound and differ from (I) due to substitutions at the phenyl ring.

In (I), the group A (C1—C6/O1) of salicylaldehyde, the central group B (C7—C9/O2) and group C (C10—C15/S1) of 2,5-dimethylthiophen-3-yl moiety are planar with r. m. s. deviation of 0.0063, 0.0267 and 0.0100 Å, respectively. The dihedral angles between A/B, A/C and B/C are 1.20 (9), 8.46 (8) and 8.27 (9)°, respectively. In the title compound, an S(6) ring motif (Bernstein et al., 1995) is formed due to intramolecular H-bonding of C—H···O type (Table 1, Fig. 2). The title compound is stabilized in the form of polymeric chains extending along the b axis due to O—H···O type of intermolecular H-bonding (Table 1, Fig. 2). The C—H···π (Table 1) and π–π interactions between the centroids of phenyl and heterocyclic rings at a distance of 3.7691 (9) Å [symmetry code: 1 - x, 1 - y, - z] also play important role in stabilizing the molecules.

Experimental top

A solution of 3-acetyl-2,5-dimethylthiophene (0.38 g, 2.5 mmol) and salicylaldehyde (0.30 g, 2.5 mmol) in an ethanolic solution of NaOH (3.0 g in 10 ml of ethanol) was stirred for 16 h at room temperature. The solution was poured into ice-cold water of pH = 2 (pH adjusted by HCl). The solid was separated and dissolved in CH2Cl2, this solution was washed with a saturated solution of NaHCO3 and then evaporated to dryness. The residue was recrystallized from methanol/chloroform.Yellow solid: Yield: 78%; m.p. 418–419 K.

Refinement top

The H-atoms were positioned geometrically (O—H = 0.86, C–H = 0.93–0.96 Å) and refined as riding with Uiso(H) = xUeq(C, O), where x = 1.5 for hydroxy & methyl and x = 1.2 for aryl H-atoms.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
