In the title compound, C11H10O3, the benzodioxole ring adopts a flattened [puckering parameters: q2 = 0.107 (2) Å, φ2 = 160 (1)°] with the methylene C atom as the flap. The crystal packing features chains, parallel to the c axis, composed of dimers connected by weak C—H–O hydrogen bonds and extending in layers in the bc plane.

A mixture of acetone (3.0 g 0.005M) and benzo[d][1,3]dioxole-5-carbaldehyde (1.5 g 0.01M) and a catalytic amount of KOH in distilled ethanol was stirred for about 12 h, the resulting mixture was concentrated to remove ethanol then poured on to ice and neutralized with dill acetic acid. The resultant solid was filtered, dried and purified by
using 1:1 mixture of ethyl acetate and petroleum ether. Recrystallized from acetone; Yield: 49% and m.pt: 412–414 K.At the end of the
the highest peak in the electron density was 0.124 e Å -3, while the deepest hole was -0.154 e Å -3.Data collection: CrysAlis PRO (Oxford Diffraction, 2009); cell

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 and its heterocyclic analogs have been used as intermediates in organic synthesis and exhibit diverse biological activities such as antimicrobial and cytotoxic agents. From a chemistry point of view, an important feature of chalcones and their heteroanalogs is the ability to act as activated unsaturated systems in conjugated addition reactions of carbanions. In continuation with our interest in the synthesis of chalcones (Loh et al., 2010) herein we report the structure of the title compound (I).
In the title compound (I) the spatial arrangement of the keto group C(10)═ O(3) and the olefinic double bond C(8)═C(9) with respect to the single bond C9—C10 is trans, as indicated the C(8)—C(9)—C(10)—O(3) torsion angle value(-176.10 (18)°). The C(8)═C(9) (1.325 (2))Å), C(9)—C(10) (1.459 (2) Å) and C10═O3 (1.225 (2) Å) distances values are similar of the structures previously reported (Gao and Ng, 2006).
Plane A is refered to C(8)/C(9)/C(10)/O(3) atoms (maximum desviation C(9) 0.0229 (17) Å). The dihedral angle between C(2)/C(7) benzene ring (maximum desviation C(4) -0.0040 (18) Å) and plane A is 7.25 (10)°. In benzodioxole ring C(1) is displaced from mean plane by 0.1351 (22) Å, forming a flattened envelope conformation with C(1) as the flap atom. The packing in the crystal structure is dominated by molecular chains made of dimers connected by C—H–O weak hydrogen bonds and extended along bc plane.
