(Received 3 November 2010; accepted 8 November 2010; online 13 November 2010)

In the mol­ecule of the title compound, C17H20N2O2, the aromatic rings are oriented at a dihedral angle of 6.23 (22)°. Intra­molecular N—H⋯O hydrogen bonding involving the amine H atom and the carbonyl O atom affects the conformation of the mol­ecule. One of the ethyl arms is disordered over two conformations, with occupancies of 0.59 (2) and 0.41 (2). The crystal packing is stabilized by inter­molecular C—H⋯O and O—H⋯O hydrogen bonds, and weak C—H⋯π inter­actions.

Comment top

Schiff bases are used as substrates in the preparation of number of industrial and biologically active compounds via ring closure, cycloaddition and replacement reactions.Some Schiff base derivatives are also known to have biological activities such as antimicrobial (El-Masry et al., 2000; Pandey et al., 1999); antifungal (Singh & Dash 1988; Varma et al., 1986); antitumor (Hodnett & Dunn 1970; Misra et al., 1981; Agarwal et al., 1983) and as herbicides (Samadhiya & Halve, 2001). In additin, Schiff bases have been used widely as ligands in the field of coordinatin chemistry (Calligaris et al., 1972). There are two caracteri properties of Schiff bases, viz. photochromism and thermochromism (Cohen et al., 1964; Moustakali-Mavridis et al., 1978). These properties result from proton transfer from the O atom to the imin N atom (Hadjoudis et al., 1987; Xu et al., 1994).

In the molecule of (I), the C13=O2 and N1—C7 bond lengths of 1.301 (2) and 1.307 (3) Å, respectively are in good agreement with those observed in 2-[(2-hydroxy-4-nitrophenyl)aminomethylene]cyclohexa-3,5-dien-1(2H)-one [1.298 (2) and 1.308 (2) Å; Ersanlı et al., 2003] and 2-Hydroxy-6-[(2-methoxyphenyl)aminomethylene]cyclohexa-2,4-dienone [1.2931 (17) and 1.3043 (19) Å; Şahin et al., 2005]. The study of Schiff bases has led to the proposal that molecules exhibiting thermochromism are planar, while those exhibiting photochromism are non-planar. This planarity of the molecule allows the proton to be transferred through the hydrogen bond in the ground state with a small energy requirement (Odabaşoǧlu et al., 2004; Hadjoudis et al., 1987). The dihedral angle between benzene rings A(C1—C6) and B(C8—C13) is 6.49 (22)° (Fig.1). These two rings are twisted slightly about the methylene amino group with torsion angles of -0.5 (3)° [C2—C1—N1—C7] and 179.48 (18)° [N1—C7—C8—C9], respectively. C16 was disordered over two positions A and B (C16A and C16B) wiht the occupancy factors refined to 0.59 (2) and 0.41 (2). Intramolecular N1—H1A···O2 hydrogen bonding contributes to the overall planarity of the molecule. In crystal packing, the weak [C5—H6···Cg1(x,- 1/2 - y, - 1/2 + z)] interaction, and the hydrogen bonds [C16A—H16A···O2(1 - x,1/2 + y,1/2 - z)] and [O1—H1A···O2(1 + x,1/2 - y,1/2 + z)] are listed in Table 1 and labelled in Fig.2.

Experimental top

The compound (Z)-6-[(4-hydroxyphenylamino)methylene]-3 -(diethylamino)cyclohexa-2,4-dienone was prepared by refluxing a mixture of a solution containing 5-(diethylamino)-2-hydroxybenzaldehyde (0.5 g, 2.59 mmol) in 20 ml e thanol and a solution containing 4-hydroxyaniline (0.28 g, 2.59 mmol) in 20 ml e thanol. The reaction mixture was stirred for 1 h under reflux. The crystals of the title compound were obtained by slow evaporation from ethyl alcohol (yield % 73; m.p. 468–470 K).

Refinement top

All H atoms were placed in calculated positions except H1A and H1B which were located in a difference fourier map. All carbon-bound H atoms were refined using a riding model with C—H = 0.93 to 0.97 Å and Uiso(H) = 1.2–1.5 Ueq (C).

Special details top

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.
