The asymmetric unit of the title compound, C₁₈H₁₆F₂N₂·H₂O, contains two independent molecules (A and B), and two independent water molecules of crystallization. In molecule A, the imidazole ring makes dihedral angles of 47.46 (7) and 60.98 (6)° with the 2,4-difluorophenyl and methylphenyl rings, respectively. The corresponding angles in molecule B are 45.85 (7) and 62.78 (7)°, respectively. The dihedral angle between the two benzene rings is 64.98 (7)° in molecule A and 65.53 (7)° in molecule B. In the crystal, the two independent molecules are linked by O—H⋯N and O—H⋯O hydrogen bonds, forming chains propagating along [100]. These chains are linked via C—H⋯F hydrogen bonds, forming slab-like two-dimensional networks lying parallel to (001).

Comment top

Imidazole derivatives have a wide range of biological properties, such as antifungal (Hori et al., 2000; Mamolo et al., 2004) and antibacterial (Khabnadideh et al., 2003) activities. They are well known analgesic (Ucucu et al., 2001), anti-inflammatory (Noilada et al., 2004), anthelmintic (Dutta et al., 2009), antiparasitic (Quattara et al., 1987), as well as antimicrobial (Sengupta & Bhattacharya, 1983) agents. In view of the interesting biological and pharmacological activities of Imidazole derivatives, the title compound was synthesized and its crystal structure is reported on herein.

The asymmetric unit of the title compound, Fig. 1, consists of two independent molecules (A and B) and two water molecules. In molecule A, the imidazole ring makes dihedral angles of 47.46 (7)° and 60.98 (6)° with the 2,4-difluorophenyl (C15-C20) and the methylphenyl rings (C8-C13), respectively, whereas in molecule B, the corresponding angles are 45.85 (7)° (C33-C38) and 62.78 (7)° (C26-C31). The dihedral angle between the two benzene rings is 65.52 (7)° in molecule A and 64.98 (6)° in molecule B.

In the crystal, the two independent molecules are linked by O—H···N and O—H···O hydrogen bonds forming chains propagating along [100]. These chains are linked via C—H···F hydrogen bonds forming slab-like two-dimensional networks lying parallel to the ab plane (Table 1 and Fig. 2).

Experimental top

To pure butane-2,3-dione (1.48 g, 15 mmol) in ethanol (10 ml), p-toluidine (1.6 g, 15 mmol), ammonium acetate (1.15 g, 15 mmol) and 2,4-difluorobenzaldehyde (1.1 g, 15 mmol) were added over about 60 min 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 column chromatography using hexane:ethyl acetate (1:1 / v:v) as the eluent [Yield: 1.93 g (46%)]. Slow evaporation of a solution of the title compound in chloroform yielded prism-like colourless crystals suitable for X-ray diffraction analysis.

Special details top

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 esds 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 > 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.
