In the title compound, C26H22ClFO2, the cyclopropane ring makes dihedral angles of 45.7 (2), 49.0 (2) and 65.2 (2)° with the fluoro-substituted phenyl ring, the benzene ring and the chloro-substituted phenyl ring, respectively. The F and Cl atoms deviate by 0.0307 (11) and 0.0652 (6) Å, respectively, from the planes of the phenyl rings to which they are attached. In the crystal, molecules are linked by C—H⋯F hydrogen bonds, forming chains along the b axis.

A mixture of 4-chloroacetophenone(0.01mole), benzaldehyde (0.01 mole), cyclopropyl 2-fluorobenzyl ketone (0.01 mole) and sodium hydroxide solution (10 ml, 10%) in ethanol (50 ml) was stirred for 3 hrs at room temperature. The solid that separated was filtered and washed with distilled water. The product was recrystallised from ethanol [Yield = 95%, M.p. = 405 - 407 K] giving block-like colourless crystals of the title compound.
The hydrogen atoms were placed in calculated positions and treated as riding atoms: C—H = 0.93 - 1.08 Å with Uiso(H) = 1.5Ueq(C) for methyl H atoms and = 1.2Ueq(C) for other H atoms.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Diketones are popular in organic synthesis for their applications in biology and medicine. They are known to exhibit antioxidant, antitumour and antibacterial activities (Bennett et al., 1999). They are also key intermediates in the preparation of various heterocyclic compounds (Sato et al., 2008). We report herein on the synthesis and crystal structure of one the title diketone.
In the title compound, Fig.1, the cyclopropane ring (C1-C3) makes a dihedral angle of 45.7 (2)° with the fluoro substituted phenyl ring (C6-C11). It makes a dihedral angle of 49.0 (2)° with the unsubstituted phenyl ring (C13-C18) and a dihedral angle of 65.2 (2)° with the chloro substituted phenyl ring (C21-C26). The fluorine atom, F1, deviates by 0.0307 (11) Å from the phenyl ring to which it is attached.
The dihedral angle between the unsubstituted phenyl ring and the fluoro substituted phenyl ring is 3.65 (8)° and the dihedral angle between the unsubstituted phenyl ring and the chloro substituted phenyl ring is 71.73 (8)°. The dihedral angle between the fluoro substituted phenyl ring and the chloro substituted phenyl ring is 71.15 (8)°. The chloro atom, Cl1, deviates by 0.0652 (6) Å from the phenyl ring to which it is attached.
In the crystal, C–H···F hydrogen bonds link the molecules to form chains along the b axis (Table 1 and Fig. 2).
