In the title compound, C29H21BrF2O3, the dihedral angles between the central anisole ring and the pendant fluorobenzene rings are 48.86 (19) and 31.89 (18)°. The dihedral angle between the anisole ring and the 1-bromo-2-methoxybenzene ring linked via the enone bridge is 82.95 (17)°.

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 3-bromo-4-methoxybenzaldehyde (0.215 g, 0.001 mol) in 30 ml e thanol, 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. Colourless blocks of (I) were grown from DMF by slow evaporation and the yield of the compound was 82%. Mp: 452 K.
H atoms were positioned geometrically [C–H = 0.9300 or 0.9600 Å] and refined using a riding model, with Uiso(H) = 1.2 Ueq (C) or 1.5Uiso(C).
As part of our ongoing studies of substituted chalcone derivatives, (Fun et al., 2010a,b), the title compound (I) was prepared and its
is reported. The precursor of the title compound was prepared from 4,4'-difluoro chalcone by several steps.The title molecule is built up (Fig. 1) from four units, namely: two fluorobenzenes (C1–C6/F1) and (C13–C18/F2), a anisole (C7–C12/O1/C28) and a 1-bromo-2- methoxybenzene (C22/C27/Br1/C29/O3). The anisole moiety makes dihedral angles of 48.86 (19)°, 31.89 (18)° and 82.95 (17)° with the two fluorobenzenes and 1-bromo-2-methoxybenzene moieties respectively.
In the crystal (Fig. 2), C29—H29B···O2 hydrogen bonds link the molecules into chains along [010].

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. |

As part of our ongoing studies of substituted chalcone derivatives, (Fun et al., 2010a,b), the title compound (I) was prepared and its crystal structure is reported. The precursor of the title compound was prepared from 4,4'-difluoro chalcone by several steps.
The title molecule is built up (Fig. 1) from four units, namely: two fluorobenzenes (C1–C6/F1) and (C13–C18/F2), a anisole (C7–C12/O1/C28) and a 1-bromo-2- methoxybenzene (C22/C27/Br1/C29/O3). The anisole moiety makes dihedral angles of 48.86 (19)°, 31.89 (18)° and 82.95 (17)° with the two fluorobenzenes and 1-bromo-2-methoxybenzene moieties respectively.
In the crystal (Fig. 2), C29—H29B···O2 hydrogen bonds link the molecules into chains along [010].
