(Received 4 December 2012; accepted 20 December 2012; online 4 January 2013)

The title compound, C₁₉H₁₄F₃NO₂, crystallizes in the keto–amine tautomeric form, with a strong intramolecular N—H⋯O hydrogen bond. The molecule is almost planar; the dihedral angle between the naphthalene ring system and the benzene ring is 4.60 (7)°. In the crystal, molecules are linked into chains along the c axis by C—H⋯O hydrogen bonds. The F atoms of the trifluoromethyl group are disordered over two positions with refined site occupancies of 0.668 (9) and 0.332 (9).

Comment top

Schiff bases often exhibit various biological activities and in many cases were shown to have antibacterial, anticancer, anti-inflammatory and antitoxic properties (Lozier et al., 1975). Schiff bases have also been used as versatile ligands in coordination chemistry (Kargar et al., 2009; Yeap et al., 2009). There are two types of intramolecular hydrogen bonds in Schiff bases, namely N—H···O in keto (NH) (Hökelek et al., 2000) and N···H—O in enol (OH) (Odabaşoǧlu et al., 2005) tautomeric forms. The present X-ray investigation shows that the title compound is a Schiff base and exists in the keto-amine form in the solid state. An ORTEP-3 (Farrugia, 2012) plot of the molecule of (I) is shown in Fig. 1. The C2—O1 bond length of 1.272 (3) Å indicates double-bond character while the N1—C11 bond length of 1.322 (3) Å indicates single-bond character. These bond distances are comparable with those of compounds previously reported as keto–amine (Özek et al., 2004; Temel et al., 2010). The dihedral angle between the naphthalene ring system and the benzene ring is 4.60 (7)°. In the crystal, molecules are linked into chains (Fig. 2) along the c axis by intermolecular C-H···O hydrogen bonds (Table 1).

Experimental top

(Z)-1-[(2-Methoxy-5-(trifluoromethyl)phenylamino)methylene]naphthalen-2(1H)-one was prepared by refluxing a mixture of a solution containing 2-hydroxy-1-naphthaldehyde (17.22 mg, 0.1 mmol) in ethanol (20 ml) and a solution containing 2-methoxy-5-(trifluoromethyl)aniline (19.12 mg, 0.1 mmol) in ethanol (20 ml). The reaction mixture was stirred for 5 h under reflux. Single crystals of the title compound for X-ray analysis were obtained by slow evaporation of an ethanol solution (Yield 84%; m.p. 472–475 K).

Special details top

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