The title mol­ecule, C17H11FN2O3, is nearly planar [maximum deviation = 0.197 (1) Å] and the mol­ecular conformation is stabilized by an N—H⋯O hydrogen bond forming an S(6) ring motif. The H atom of the intra­molecular hydrogen bond was found to be disordered over two sites and thus both the hy­droxy and keto tautomers are simultaneously present in the solid. Refinement of the occupancy of this site suggests that the hy­droxy form is the major component [occupancy refined to 0.59 (3):0.41 (3)]. Bond lengths are also largely consistent with dominance of the hy­droxy form. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming layers parallel to (101). ππ stacking inter­actions [centroid–centroid distances = 3.5649 (9) and 3.7579 (9) Å] inter-connect these layers.

Comment top

Schiff bases have been widely studied due to their importance in industrial and biological applications. They serve for example as, antibacterial, antifungal, anticancer (Sari et al., 2003, Verma et al., 2004) and herbicidal agents (Cozzi, 2004; Chandra & Sangeetika, 2004). It is well known that the introduction of fluorine atom into an organic molecule causes dramatic changes in its biological profile (Blair et al., 2000), mainly due to the high electronegativity of fluorine. Incorporating fluorine increases fat solubility, improving the drug's partitioning into membranes and hence increasing bioavailability (LeBars et al., 1987). Fluorination can also aid hydrophobic interactions between the drug and binding sites on receptors or enzymes (Kirk et al., 1979). Further to our study in synthesis of fluorinated bioactive compounds we herein report the synthesis and crystal structure of the title compound.

As seen in Fig. 1, the title molecule (I) is nearly planar with maximum deviations of 0.197 (1) Å for O3, -0.157 (1) Å for C9 and 0.145 (2) Å for C6. The napthalene ring system (C1–C10) makes a dihedral angle of 5.04 (6) ° with the the benzene ring (C12–C17) of the 1-fluoro-4-nitrobenzene group. The C1–C11–N1–C12, F1–C13–C12–N1, O1–C2–C1–C11, O2–N2–C16—C17 and O3–N2–C16 C15 torsion angles are -179.56 (13), -179.39 (13), 2.4 (2), -8.9 (2) and -9.7 (2) °, respectively. All bond lengths and angles are similar to those of a related structure previously reported (Akkurt et al., 2012).

An N—H···O hydrogen bond stabilizes the molecular conformation of (I) forming an S(6) ring motif (Bernstein et al., 1995; Fig. 1). In the crystal structure, C—H···O hydrogen bonds (Table 1, Fig. 2) link the molecules to each other, forming two dimensional layers parallel to (101) (Fig. 3). In addition, these layers connect to each other by π-π stacking interactions [Cg1···Cg3iii = 3.5649 (9) Å and Cg3···Cg3iv = 3.7579 (9) Å; where symmetry codes (iii) = x, 1/2 - y, 1/2 + z and (iv) = 1 - x, 1 - y, 1 - z; Cg1 and Cg3 are the centroids of the C1–C5/C10 and C12–C17 benzene rings, respectively].

Experimental top

The title compound was obtained unintentionally in a good yield from a three components reaction by heating of 1 mmol (172 mg) 2-hydroxynaphthalene-1-carbaldehyde, 1 mmol (156 mg) 2-fluoro-5-nitroaniline and 1 mmol (188 mg) 5-phenylcyclohexane-1,3-dione in ethanol for 8 h at 350 K. The solvent was evaporated under vacuum and the resulting solid was crystallized from a mixture of ethanol and few drops of acetone. Yellow rods of product (M.p. 471 K) were collected (73% yield) of sufficient quality for X-ray diffraction.

Refinement top

Difference synthesis suggested a disordered model for H1 was appropriate. Refinement over two sites with thermal displacement ellipsoids constrained to be equal and with both O1—H1 and N1—H2 distances restrained to 0.88 (1) A gave a model with 0.59 (3):0.41 (3) site occupancy in favour of the OH form. The C-bound H atoms were placed in geometrically optimized positions and constrained to ride on their parent atoms with C—H = 0.95 (aromatic) Å and with Uiso(H) = 1.2Ueq(C).

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 on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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.
