In the molecule of the title compound, C17H13ClF2O3, the dihedral angles formed by the aromatic rings of the chlorobenzene and difluorobenzene groups with the plane of the acrylate unit are 48.85 (12) and 9.07 (14)°, respectively. In the molecules are linked by weak intermolecular C—H⋯O hydrogen-bond interactions, forming chains along the c axis.

An equimolar solution of ethyl 3-bromo-2-(4-chlorophenyl)acrylate and 2,4-difluorophenol in chloroform was left to react overnight at room temperature. Block-shaped crystals suitable for X-ray analysis were obtained by slow evaporation of the solvent in air for five days.
H atoms were included in the riding model approximation with C–H = 0.93–0.97 Å and with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(C) for methyl H atoms.

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. |

Recently, the synthesis and structure of a number of etheric compounds have been widely investigated (Li, Xue et al., 2008; Li, Wang & Jian, 2008; Lin & Jian, 2008; Liu et al., 2008). We report herein the crystal structure of the new title compound.
In the molecule of the title compound (Fig. 1), the dihedral angles between the aromatic rings of the chlorobenzene and difluorobenzene groups with the plane of the acrylate unit are 48.85 (12) and 9.07 (14)° respectively. All the bond lengths (Allen et al., 1987) and angles are not unusual. In the crystal structure, molecules are linked by weak intermolecular C—H···O hydrogen interactions forming chains along the c axis (Table 1).
