The asymmetric unit of the title compound, C14H11FN2O, contains two independent mol­ecules, both of which adopt the E conformation with respect to the azomethine C=N bond. The mol­ecules are non-planar, with dihedral angles of 26.92 (12) and 11.36 (11)° between the benzene and phenyl rings. In the crystal, mol­ecules are linked through N—H⋯O=C and N—H⋯N hydrogen bonds into chains along [101]. C—H⋯O contacts link these chains into layers parallel to (001). The three-dimensional crystal packing is stabilized by ππ inter­actions, the shortest separation between the centroids of benzene rings being 3.884 (1) Å.

Comment top

The coordination chemistry of acyl and aroyl hydrazones have been a subject of competitive research as they are multipurpose class of ligands. Apart from exhibiting physiological and biological activities (Sreeja et al., 2004), they also function as catalysts (Heravi et al., 2007) as well as inhibitors for many enzymes (Tamasi et al., 2005).

The title compound crystallizes in monoclinic space group P21/n. The asymmetric unit contains two molecules, both of which adopt the E configuration with respect to the CN bond (Fig. 1). They exist in the amido form with a C8O1 bond length of 1.231 (2) Å and C22O2 of 1.223 (2) Å, which are very close to the reported CO bond length in closely related structure (Nair et al., 2012). Both molecules adopt the Z conformation with respect to the amido C—N bonds, with torsion angles of -7.2 (3)° and 5.5 (3)°.

There are eight intermolecular hydrogen bonding interactions, out of which three are classical and the rest of interactions are non-classical with D···A distances of 2.875 (2), 3.339 (2), 2.882 (2), 3.213 (2), 3.402 (3), 3.450 (3), 3.250 (2) and 3.312 (2) Å (Table 1). The hydrogen at the N2 atom forms bifurcated H bonds with the O2 and N3 atoms of the adjacent molecules (Fig. 2). Two ππ interactions between the rings C15—C20 & C23—C28 (shown in blue) and between the two C23—C28 rings (shown in pink) of the adjacent molecules with the intercentroid distances of 3.8840 (14) Å and 3.9145 (14) Å, respectively, also link the molecules (Fig. 3). Fig. 4 shows the packing of the molecules by means of hydrogen bonding and ππ interactions.

Experimental top

The title compound was prepared by adapting a reported procedure (Mangalam & Kurup, 2011). Benzoic acid hydrazide (1 mmol, 0.136 g) was dissolved in methanol and refluxed with methanolic solution of 2-fluorobenzaldehyde (1 mmol 0.124 g), in presence of a few drops of glacial acetic acid for 6 h. On cooling the reactant media, crystals of hydrazone were separated out. The crystals were filtered and washed with minimum quantity of methanol and dried over P4O10 in vacuo. Good quality crystals suitable for X-ray analysis were obtained from methanolic solution by slow evaporation.

Refinement top

All H atoms on C were placed in calculated positions, guided by difference maps, with C—H bond distances of 0.93 Å. H atoms were assigned Uiso(H) values of 1.2Ueq(carrier). H atoms of N2—H2' and N4—H4' bonds were located from difference maps and the bond distances are restrained to 0.88±0.01 Å.

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 > 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.
