In the title compound, C28H19F3O2, the central benzene ring forms dihedral angles of 48.69 (6), 60.93 (6) and 42.06 (6)° with the fluorobenzene rings. In the crystal, intermolecular C—H⋯O and C—H⋯F hydrogen bonds link the molecules, forming an undulating two-dimensional network parallel to the bc plane. C—H⋯π interactions further consolidate the crystal packing.

To a mixture of 1-(4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl) ethanone (0.338 g, 0.001 mol) and 2-fluorobenzaldehyde (0.124 g, 0.001 mol) in 30 ml ethanol, 0.5 ml of 10% sodium hydroxide solution was added and stirred at 5–10°C for 3 h. The precipitate formed was collected by filtration and purified by recrystallization from ethanol. The single-crystal was grown from methanol by slow evaporation method and yield of the compound was 74%. M.p.: 453 K.
All the H atoms were positioned geometrically and were refined with a riding model with Uiso(H) = 1.2 or 1.5 Ueq(C) (C—H = 0.95 or 0.98 Å). A rotating group model was applied to the methyl group. In the final
one outliner (-13 1 30) was omitted.In continuation of our work on synthesis of terphenyl
(Fun et al., 2011), the title compound is prepared and its is reported. The starting material of the title compound was prepared from 4,4'-difluoro chalcone by several steps (Fun, Hemamalini et al., 2012).In the title compound (Fig. 1), the central benzene ring (C7–C12) forms dihedral angles of 48.69 (6), 60.93 (6) and 42.06 (6)°, respectively, with the fluorobenzene rings C1–C6/F1, C16–C21/F3 and C22–C27/F2. Bond lengths and angles are within the normal ranges and are comparable with the related structure (Fun, Loh et al., 2012).
In the crystal packing (Fig. 2), intermolecular C4—H4A···O2 and C19—H19A···F2 hydrogen bonds (Table 1) link the molecules to form undulating two-dimensional network parallel to the bc plane. C—H···π interactions (Table 1), involving the central benzene ring, further consolidate the crystal packing.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
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. |

In continuation of our work on synthesis of terphenyl chalcones (Fun et al., 2011), the title compound is prepared and its crystal structure is reported. The starting material of the title compound was prepared from 4,4'-difluoro chalcone by several steps (Fun, Hemamalini et al., 2012).
In the title compound (Fig. 1), the central benzene ring (C7–C12) forms dihedral angles of 48.69 (6), 60.93 (6) and 42.06 (6)°, respectively, with the fluorobenzene rings C1–C6/F1, C16–C21/F3 and C22–C27/F2. Bond lengths and angles are within the normal ranges and are comparable with the related structure (Fun, Loh et al., 2012).
In the crystal packing (Fig. 2), intermolecular C4—H4A···O2 and C19—H19A···F2 hydrogen bonds (Table 1) link the molecules to form undulating two-dimensional network parallel to the bc plane. C—H···π interactions (Table 1), involving the central benzene ring, further consolidate the crystal packing.
