In the title compound, C15H10Cl2O2, the dihedral angle between the mean planes of the two benzene rings is 7.7 (6)°. The crystal packing is influenced by O—H⋯O hydrogen bonds, which form chains along [010]. Weak π–π stacking interactions [centroid–centroid distance = 3.6697 (13) Å] are observed, which may contribute to the crystal packing stability.

To a mixture of 2-hydroxybenzaldehyde (1.22 g, 0.01 mol) and 3,4-dichloroacetophenone (1.89 g, 0.01 mol) in ethanol (40 ml), 10 ml of 10% sodium hydroxide solution was added and stirred at 278–288 K for 3 h. The precipitate formed was collected by filtration and purified by recrystallization from ethanol. Single crystals were grown from DMF by the slow evaporation method. The yield of the compound was 86%. (M.P.: 392 K).
The H2O atom was located by a difference map and refined isotropically with DFIX = 0.85 (2) Å. All of the remaining H atoms were placed in their calculated positions and then refined using the riding model with C—H lengths of 0.93 Å. Isotropic displacement parameters for these atoms were set to 1.19–1.20 (CH) times Ueq of the parent atom.

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. |

Chalcones are abundant in edible plants and considered as the precursors of flavonoids and isoflavonoids. They have also been shown to display a diverse array of pharmacological activities (Dhar, 1981; Nowakowska, 2007) including anti-infective, anti-inflammatory, antimicrobial, antifungal, antioxidant, cytotoxic, antitumor, anticancer and mutagenic properties (Dimmock et al., 1999; Cheng et al., 2008; Bandgar et al., 2010). The basic skeleton of chalcones which possess an α,β-unsaturated carbonyl group is a useful synthone for the synthesis of various biodynamic cyclic derivatives such as pyrazoline, isoxazoline, 2,4,6-triaryl pyridine, benzodiazepine and cyclohexenone derivatives (Samshuddin et al., 2010; 2011; Fun et al., 2010; Jasinski et al., 2010; Baktır et al., 2011). The crystal structures of some chalcones, viz., (2E)-3-[3-(benzyloxy)phenyl]-1-(2-hydroxyphenyl)prop-2-en-1-one (Fun et al., 2011), (2E)-3-(4-chlorophenyl)-1-(4-hydroxyphenyl) prop-2-en-1-one (Jasinski et al., 2011), have been reported. In continuation of our studies on chalcones and their derivatives, the title compound (I) was prepared and its crystal structure is reported.
In the title compound, C15H10Cl2O2, the dihedral angle between the mean planes of the two benzene rings is 7.7 (6)° (Fig. 1). O—H···O hydrogen bonds (Table 1) are observed between the hydroxyl hydrogen and propene oxygen atoms forming 1-D polymeric chains along [010]. In addition, weak π–π stacking interactions (Cg1···Cg2 distance of 3.6697 (13) Å; Cg1 and Cg2 are the centroids of the C1–C5 ring and C10–C15 ring, respectively) are observed which may contribute to crystal packing stability.
