In the title compound, C29H22F2O2S, the central benzene ring makes dihedral angles of 45.83 (7), 38.90 (7) and 55.50 (7)° with the two fluoro-substituted benzene rings and the methylsulfanyl-substituted benzene ring, respectively. In the crystal, C—H⋯O contacts connect the molecules into layers lying perpendicular to the c axis. In addition, π–π stacking interactions between one of the fluorophenyl groups [centroid–centroid distances = 3.681 (1) and 3.818 (1) Å] are observed.

To a mixture of 1-(4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)ethanone (0.338 g, 001 mol) and 4-(methylsulfanyl)benzaldehyde (0.152 g, 0.001 mol) in 30 ml ethanol, 0.5 ml of 10% sodium hydroxide solution was added and the reaction mixture was stirred at 5–10°C for 3 hrs. The precipitate formed was collected by filtration and purified by recrystallization from ethanol ( yield 72%; m.p. 407 K). Single-crystal was grown from DMF by slow evaporation method.
All H atoms were positioned geometrically and were treated as riding on their parent C atoms, with C—H distances of 0.93–0.96 Å and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).
The pharmacological importance of terphenyls is well documented (Gill & Steglich, 1987; Liu, 2006). The
of some terphenyl viz. (E)-1-(4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)-3-(6-methoxy naphthalen-2-yl)prop-2-en-1-one (Fun et al., 2011), (2E)-1- (4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)-3-(2-fluorophenyl) prop-2-en-1-one (Fun, Hemamalini et al., 2012) and (E)-3-(2-chlorophenyl) -1-(4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)prop-2-en-1-one (Samshuddin et al., 2012) have been reported. In view of the importance of terphenyls, the title compound (I) was prepared from 4,4'-difluoro chalcone by several steps (Fun, Loh et al., 2012) and its is reported here.All bond lengths and angles are normal and correspond to those observed in related structures. The central benzene ring forms dihedral angles of 45.83 (7), 38.90 (7) and 55.50 (7) ° with the two fluoro- substituted benzene rings and methylsulfanyl substituted benzene ring, respectively. In the crystal, molecules are connected via intermolecular C—H···O hydrogen bonds (Fig.2) to form layers. The π-π interactions between the benzene ring (C10—C15) of the molecule at (x, y, z) and the same benzene ring of inversion related molecules at (2 - x, -1 - y, -z) [centroid separation = 3.681 (1) Å, = 3.512 Å and centroid shift = 1.102 Å] and (1 - x, -1 - y, -z) [centroid separation = 3.818 (1) Å, = 3.379 Å and centroid shift = 1.777 Å].

Experimental. CrysAlis PRO, Oxford Diffraction Ltd., Version 1.171.34.40 (release 27–08-2010 CrysAlis171. NET) (compiled Aug 27 2010,11:50:40) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm. |
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. |

The pharmacological importance of terphenyls is well documented (Gill & Steglich, 1987; Liu, 2006). The crystal structure of some terphenyl chalcones, viz. (E)-1-(4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)-3-(6-methoxy naphthalen-2-yl)prop-2-en-1-one (Fun et al., 2011), (2E)-1- (4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)-3-(2-fluorophenyl) prop-2-en-1-one (Fun, Hemamalini et al., 2012) and (E)-3-(2-chlorophenyl) -1-(4,4''-difluoro-5'-methoxy-1,1':3',1''-terphenyl-4'-yl)prop-2-en-1-one (Samshuddin et al., 2012) have been reported. In view of the importance of terphenyls, the title compound (I) was prepared from 4,4'-difluoro chalcone by several steps (Fun, Loh et al., 2012) and its crystal structure is reported here.
All bond lengths and angles are normal and correspond to those observed in related structures. The central benzene ring forms dihedral angles of 45.83 (7), 38.90 (7) and 55.50 (7) ° with the two fluoro- substituted benzene rings and methylsulfanyl substituted benzene ring, respectively. In the crystal, molecules are connected via intermolecular C—H···O hydrogen bonds (Fig.2) to form layers. The crystal structure is further stabilized by π-π interactions between the benzene ring (C10—C15) of the molecule at (x, y, z) and the same benzene ring of inversion related molecules at (2 - x, -1 - y, -z) [centroid separation = 3.681 (1) Å, interplanar spacing = 3.512 Å and centroid shift = 1.102 Å] and (1 - x, -1 - y, -z) [centroid separation = 3.818 (1) Å, interplanar spacing = 3.379 Å and centroid shift = 1.777 Å].
