1-(5-hydroxy-2,2-dimethyl-2H-chromen-6-yl)ethanone(2.182 g,10 mmol), 4-chlorobenzaldehyde(1.962 g, 10 mmol) in ethanal KOH (20% w/v aqueous solution) and the mixture was stirred at 273 K for 10 h. The the crude product was recrystallized from ethanol to give (I). Single crystals suitable for X-ray
were grown by slow evaporation of a diethyl ether solution of (I) at room temperature.H atoms were positioned geometrically (C—H = 0.93–0.96 Å, O—H = 0.86 Å) and constrained to ride on their parent atoms in a riding-model approximation, with Uiso(H) = 1.2eq(C) or 1.5Ueq(Cmethyl,O).

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 (1,3-diaryl-2-propen-1-ones) are stucturally simple compounds of the flavonoid family which display an impressive array of biological properties such as anticancer (Rao et al., 2004; Tran et al., 2009), antileishmanial (Boeck et al., 2006), antifungal activity (Opletalova & Sedivy, 1999) and antioxidant activity (Dimmock et al., 1999). Chalcones can be easily obtained from the adol condensation of aromatic aldehydes and aromatic ketones. The crystal structure of related compounds:(E)-1-(5-Hydroxy-2,2-dimethl-2H-chromen-6-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (Wang et al., 2011) and (2E)-1-(2-Bromoppheny)-3-(3,4,5-trimethoxypheny)prop-2-en-1-one (Jasinski et al., 2009) have been reported recently. The crystal structure of the title compound (I) is reported in this paper.
The asymmetric unit of (I) consists of two crystallographically independent molecules (Fig. 1). The bond distances are normal and are comparable with a closely related structure (Wang et al., 2011). Each molecule of (I) exists in an E configuration with respect to the C7═C8 double bond. The dihedral angles between the two benzene rings in each molecule are 7.17 (11)° [C21—C26/C30—C35] and 9.82 (11)° [C1—C6/C10—C15]. In both independent molecules, the hydroxy group is invovled in an intramolecular O—H···O hydrogen bond.
