(Received 13 January 2010; accepted 25 January 2010; online 30 January 2010)

The mol­ecule of the title compound, C15H15NO2, adopts the enol–imine tautomeric form and has a strong intra­molecular O—H⋯N hydrogen bond as a result. The mol­ecule is almost planar, with a maximum deviation of 0.1038 (15) Å for the meth­oxy C atom. A weak C—H⋯π inter­action and a weak C—H⋯O hydrogen bond are present in the crystal.

Comment top

Schiff bases are formed by reaction of a primary amine and an aldehyde and have a wide area of usage as ligands in coordination chemistry. Especially o-hydroxy Schiff base derivatives are important classes and have attracted the interest of chemists and physicist because of their photochromic and thermochromic features in the solid state. These features are caused by the proton transfer to N atom from O atom with light in photochromic or with temperature in thermochromic Schiff bases. It has been claimed that the molecules showing thermochromism are planar and showing photochromism are non-planar (Moustakali-Mavridis et al., 1980). In general, o-hydroxy Schiff bases can be found at two possible tautomeric forms called as phenol-imine and keto-amine. Depending on these tautomers, two different types of intramolecular hydrogen bonding are visible in o-hydroxy Schiff bases: O—H···N in phenol-imine and N—H···O in keto-amine tautomers.

The molecular structure of the title compound is almost planar with maximum deviation of 0.1038 (15) Å for methyl C7 and exhibits an enol-imine tautomeric form, as indicated by the following bond lengths: C8═N1 [1.2757 (15) Å], C1—C8 [1.4514 (16) Å] and C2—O1 [1.3509 (15) Å]. These bond lengths are in a good agreement with observed for (E)-2-[(4-chlorophenyl)iminomethyl]-5-methoxyphenol [1.282 (2), 1.436 (2) and 1.3452 (18) Å; Koşar et al., 2009], which is also an enol-imine tautomer. The same bond lengths are comparable with observed for (E)-2-[(2-hydroxy-5-nitrophenyl)-iminomethyl]-4-nitrophenolate (1.288, 1.420 and 1.2749 Å; Tanak & Yavuz, 2010), which is a keto-amine tautomer.

As a result of enol-imine form of the molecule, there is a strong intramolecular hydrogen bond between O1 and N1 (Fig. 1). The three dimensional crystal structure is stabilized by one weak C—H···π interaction (Cg1 is the centroid of the C9–C14 ring) and one weak C—H···O hydrogen bond (between C7 and O2 of neighbor molecule) and van der Waals interactions (Figs. 2 & 3). Both intramolecular and intermolecular hydrogen bonding geometries can be seen in Table 1.

Experimental top

The compound (E)-4-methoxy-2-[(p-tolylimino)methyl]phenol was prepared by reflux a mixture of a solution containing 5-methoxysalicylaldehyde (0.5 g, 3.3 mmol) in 20 ml ethanol and a solution containing 4-methylaniline (0.35 g, 3.3 mmol) in 20 ml ethanol. The reaction mixture was stirred for 1 h under reflux. The crystals of (E)-4-methoxy-2-[(p-tolylimino)methyl]phenol suitable for X-ray analysis were obtained from benzene by slow evaporation (yield 81%; m.p. 377–378 K).

Refinement top

All H atoms except for H1 were refined using a riding model, with C—H distances of 0.96 Å for the methyl group and 0.93 Å for the aromatic groups. The displacement parameters of these H atoms were fixed at 1.2Ueq of their parent carbon atom for the aromatic groups and 1.5Ueq of their parent atoms for the methyl group.

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