In the title molecule, C27H19FN2, the imidazole ring is essentially planar [maximum deviation = 0.004 (1) Å] and makes dihedral angles of 62.80 (6), 36.98 (6), 33.16 (6) and 46.24 (6)°, respectively, with the substituent rings in the 1-, 2-, 4- and 5-positions. No classical hydrogen bonds are observed in the crystal structure.

To benzil (3.15 g, 15 mmol) in ethanol (10 ml), aniline (1.5 g, 15 mmol), ammonium acetate (7 g, 15 mmol) and p-fluorobenzaldehyde (1.7 g, 15 mmol) were added over about 1 h while maintaining the temperature at 333 K. The reaction mixture was refluxed for 7 days and extracted with dichloromethane. The solid that separated was purified by
using hexane: ethyl acetate as the Yield: 3.51 g (60%).H atoms were positioned geometrically and allowed to ride on their parent atoms with C—H = 0.93 Å, and with Uiso(H) = 1.2Ueq(parent atom).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
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. |

Nagalakshmi (2008) has reported synthesis and pharmacological evaluation of 2-(4-Halo substituted phenyl)-4,5-diphenyl-1H-imidazoles, and Dooms-Goossens et al. (1995) have reported contact allergy to imidazoles used as antimycotic agents. As part of our research (Gayathri et al., (2010a,b,c)), we have synthesized the title compound (I) and report its crystal structure here.
In (I), Fig. 1, the imidazole ring is essentially planar [maximum deviation = 0.004 (1) Å for N1]. The imidazole ring makes dihedral angles of 62.80 (6), 36.98 (6), 33.16 (6) and 46.24 (6) ° with the phenyl (C11—C16) attached to N1, fluorophenyl (C21—C26) attached to C2, and two phenyl rings (C41—C46) & (C51—C56) attached to C4 and C5, respectively. The phenyl ring at N1 makes dihedral angles of 54.26 (6), 85.21 (7) and 65.02 (6) ° with the fluorophenyl at C2, and phenyl rings attached to C4 and C5, respectively. The fluorophenyl ring makes dihedral angles of 63.01 (6) and 78.99 (6) ° with the phenyl rings at C4 and C5, respectively. Finally, the dihedral angle between the phenyl rings at C4 and C5 is 51.10 (6) °. In the crystal structure no classical hydrogen bonds are observed.
