(Received 9 May 2010; accepted 10 May 2010; online 15 May 2010)

The title mol­ecule, C16H13ClO2, is trans with respect to the C=C double bond. The dihedral angles between the mean plane of the prop-2-en-1-one unit and those of the 3-chloro- and 4-meth­oxy-substituted benzene rings are 20.93 (9) and 20.42 (10)°, respectively, and the dihedral angle between the mean planes of the two benzene rings is 40.96 (5)°. The crystal structure is stabilized by weak inter­molecular C—H⋯O hydrogen bonds, forming chains along the b axis.

Comment top

Chalcones are well known for their biological activities (Dimmock et al., 1999). These have been reported as potential anti-fungal chemotherapeutic (Opletalova & Sedivy, 1999), anti-tuberculosis (Lin et al., 2002) and anti-infective & anti-inflammatory agents (Nowakowska, 2007). In addition, few among these have found their use as organic non-linear optical materials (NLO) due to their good SHG (second-harmonic generation) conversion efficiencies (Sarojini et al., 2006; Poornesh et al., 2009; Shettigar et al., 2006; 2008). In continuation of our work on chalcones (Hussain et al., 2009) and in view of the importance of chloro chalcones, the synthesis and crystal structure of the title compound, (I), is presented in this article.

The title molecule (Fig. 1) exhibits an E configuration with respect to the C═C double bond, the torsion angle C–C═C–C being -177.75 (17)°. The dihedral angle between the mean planes of the 3-chloro and 4-methoxy substituted benzene rings is 40.96 (5)°. The dihedral angles between the mean planes of the prop-2-en-1-one unit and those of the 3-chloro and 4-methoxy substitued benzene rings are 20.93 (9) and 20.42 (10)°, respectively. The geometrical parameters for (I) are consistent with those of some recently reported chalcone derivatives closely related to (I) (Rosli et al., 2006; Patil et al., 2006; Harrison et al., 2006; Fun et al.; 2008; Jasinski et al., 2010). The structure is stabilized by intermolecular interactions of the type C—H···O resulting in polymeric chains along the b-axis (Fig. 2, Tab. 1)

Experimental top

A mixture of 3-chlorobenzaldehyde (0.01 moles, 1.13 g), 4-methoxyacetophenone (0.01 moles, 1.37 ml) and sodium hydroxide solution (10%, 30 ml) was stirred at room temperature for 6 hrs. Precipitates obtained were poured into ice-cold water (500 ml) and left to stand for 2 hours followed by filtration of the resultant solid which was dried and crystallized from ethanol by slow evaporation.

Refinement top

The H-atoms were clocated from difference Fourier maps and were included in the refinement at geometrically idealized positions in riding-model approximation with C—H = 0.95 and 0.98 Å for aryl and methyl type H-atoms, respectively; the Uiso(H) were allowed at 1.2Ueq(C). The final difference map was essentially featurless.

Special details top

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 > 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.
