Abstract
In the title compound, C18H17FO4, the dihedral angle between the aromatic rings is 32.29 (8)°. The C atoms of the methoxy groups deviate from their attached ring plane by 0.018 (2), −0.006 (2) and −0.094 (2) Å. In the crystal, C—H⋯O hydrogen bonds link the molecules into C(6) [001] chains.

Comment
As part of our ongoing studies of chalcones with possible biological activity (Rimal et al., 2012), we now describe the crystal structure of 1-(2-fluorophenyl)-3-(2,4,6-trimethoxyphenyl)prop-2-en-1-one, (I).
The ORTEP drawing of the title molecule is as shown in Fig. 1. The dihedral angle between the aromatic rings of 2-flurophenyl and trimethoxy phenyl group is 32.29 (8)°. Mean plane of prop-2-ene-1 one moiety makes an angle of 37.65 (9)° with 2-flurophenyl and 11.64 (9)° with trimethoxyphenyl moiety. The overall geometry of the title compound is similar to that of (2E)-1-(4-fluorophenyl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one (Jasinski et al., 2009).
The molecules are connected by C—H···O interactions (Fig. 2).
Experimental
The title compound was synthesized as per the procedure reported in the literature (Rimal et al., 2012). The final product was obtained by recrystallization using aqueous ethyl acetate: methanol as a solvent. Slow evaporation method yielded brown blocks.
Refinement
All the hydrogen atoms of the compound are fixed geometrically (C—H= 0.93–0.97 Å) and allowed to ride on their parent atoms.

Special details
| 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 on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |
