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 6-methoxy-2-naphthaldehyde (0.188 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 hours. The precipitate formed was collected by filtration and purified by recrystallization from ethanol. Single crystals were grown from DMF by slow evaporation method and the yield of the compound was 84% (m.p. 479K).
All hydrogen atoms were positioned geometrically (C—H = 0.93 or 0.96 Å) and were refined using a riding model, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). A rotating group model was applied to the methyl groups.
Chalcones are highly reactive substances of varied nature. They have been reported to possess many interesting pharmacological properties (Dhar, 1981) including anti-inflammatory, antimicrobial, antifungal, antioxidant, cytotoxic, antitumor and anticancer activities (Dimmock et al., 1999; Satyanarayana et al., 2004). α,β-unsaturated carbonyl group is a useful synthone for the synthesis of various biodynamic cyclic derivatives such as pyrazoline, benzodiazepine, 2,4,6-triarylpyridine, isoxazoline and cyclohexenone derivatives. Polysubstituted aromatics are key structures of great efficacy in synthetic, medicinal and natural product chemistry. In recent years, it has been reported that some terphenyls exhibit considerable biological activities, e.g., potent anticoagulant, immunosuppressants, anti-thrombotic, neuroprotective, specific 5-lipoxygenase inhibitory and cytotoxic activities (Liu, 2006). Due to their promising biological activities and important properties, terphenyls have generated increasing research interests. As such, the synthesis of polysubstituted aromatics has been a fascinating area in organic chemistry (Astruc, 2002).
also find application as organic nonlinear optical materials (NLO) for their SHG conversion efficiency (Sarojini et al., 2006). The basic skeleton of which possessIn view of the pharmacological importance of terphenyls and

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

Chalcones are highly reactive substances of varied nature. They have been reported to possess many interesting pharmacological properties (Dhar, 1981) including anti-inflammatory, antimicrobial, antifungal, antioxidant, cytotoxic, antitumor and anticancer activities (Dimmock et al., 1999; Satyanarayana et al., 2004). Chalcones also find application as organic nonlinear optical materials (NLO) for their SHG conversion efficiency (Sarojini et al., 2006). The basic skeleton of chalcones which possess α,β-unsaturated carbonyl group is a useful synthone for the synthesis of various biodynamic cyclic derivatives such as pyrazoline, benzodiazepine, 2,4,6-triarylpyridine, isoxazoline and cyclohexenone derivatives. Polysubstituted aromatics are key structures of great efficacy in synthetic, medicinal and natural product chemistry. In recent years, it has been reported that some terphenyls exhibit considerable biological activities, e.g., potent anticoagulant, immunosuppressants, anti-thrombotic, neuroprotective, specific 5-lipoxygenase inhibitory and cytotoxic activities (Liu, 2006). Due to their promising biological activities and important properties, terphenyls have generated increasing research interests. As such, the synthesis of polysubstituted aromatics has been a fascinating area in organic chemistry (Astruc, 2002).
In view of the pharmacological importance of terphenyls and chalcones, and in continuation of our work on synthesis of various derivatives of 4,4'-difluorochalcone (Samshuddin, Narayana et al., 2011; Samshuddin, Butcher et al., 2011; Fun et al., 2010a,b; Jasinski et al., 2010a,b; Baktır et al., 2011a,b), the title compound (I) is prepared and its crystal structure is reported. The precursor of the title compound was prepared from 4,4'-difluorochalcone using several steps.
The asymmetric unit of the title compound as shown in Fig. 1. The naphthalene (C1–C10) ring system is approximately planar with a maximum deviation of 0.055 (2) Å for atom C10. The central benzene (C14–C19) ring makes dihedral angles of 44.71 (10), 47.80 (10) and 63.68 (9)° with the attached two fluoro-substituted benzene (C20–C25 and C26–C31) rings and the naphthalene (C1–C10) ring system, respectively.
In the crystal structure, (Fig. 2), the molecules are connected via intermolecular C—H···F and C—H···O hydrogen bonds. Furthermore, the crystal structure is stabilized by a weak π–π interaction between the benzene (C26–C31) rings [Cg···Cg(-x, -y, 2 - z) = 3.6816 (13) Å] and C—H···π (Table 1) interactions, involving the centroids of the C1–C3/C8–C10 (Cg1), C14–C19 (Cg3) and C20–C25 (Cg4) rings.
