(E)-2-[(3,5-Di-tert-butyl-2-hydroxybenzylidene)amino]benzonitrile

J.-C. Zhou, N.-X. Li, C.-M. Zhang and Z.-Y. Zhang

The asymmetric unit of the title compound, C₂₂H₂₆N₂O, contains three crystallographically independent molecules, in which the aromatic rings are oriented at dihedral angles of 21.74 (5), 27.59 (5) and 27.87 (5)°. Intramolecular O—H

N hydrogen bonds result in the formation of planar six-membered rings, and these are nearly coplanar with the adjacent rings. In the crystal structure, π–π contacts between the benzene rings [centroid–centroid distances = 3.989 (2), 3.802 (1) and 3.882 (1) Å] may stabilize the structure.

Comment top

Schiff base compounds have received considerable attention for many years, primarily due to various pharmacological activities, such as anticancer (Dao et al., 2000) and anti-HIV (Sriram et al., 2006). In addition, Schiff base compounds play important roles in the development of coordination chemistry related to magnetism (Weber, et al., 2007) and catalysis (Chen, et al., 2008). We report herein the crystal structure of the title compound.

The asymmetric unit of the title compound contains three crystallographicaly independent molecules (Fig. 1), in which the bond lengths (Allen et al., 1987) and angles are within normal ranges. Rings A (C1-C6), B (C16-C21), C (C23-C28), D (C38-C43), E (C45-C50) and F (C60-C65) are, of course, planar and the dihedral angles between them are A/B = 21.74 (5), C/D = 27.59 (5) and E/F = 27.87 (5) °. Intramolecular O-H···N hydrogen bonds (Table 1) results in the formations of planar six-membered rings G (O1/N1/C1/C2/H1A), H (O2/N3/C23/C24/C37/H2A) and I (O3/N5/C45/C50/C59/H3A), in which they are oriented with respect to the adjacent rings at dihedral angles of A/G = 1.23 (5), C/H = 1.07 (5) and E/I = 1.30 (5) °.

In the crystal structure, the π–π contacts between the benzene rings, Cg1—Cg4ⁱ, Cg2—Cg3ⁱ and Cg5—Cg6ⁱⁱ, [symmetry codes: (i) x, y - 1, z, (ii) 1 - x, 1/2 + y, 1/2 - z, where Cg1, Cg2, Cg3, Cg4, Cg5 and Cg6 are centroids of the rings A (C1-C6), B (C16-C21), C (C23-C28), D (C38-C43), E (C45-C50) and F (C60-C65), respectively] may stabilize the structure, with centroid-centroid distances of 3.989 (2), 3.802 (1) and 3.882 (1) Å, respectively.

Experimental top

For the preparation of the title compound, 3,5-di-tert-butyl-2 -hydroxybenzaldehyde (0.936 g, 4 mmol) and 2-aminobenzonitrile (0.531 g, 4.5 mmol) were dissolved in ethanol (25 ml). The mixture was heated to reflux for 6 h, and then cooled to room temperature. The solution was filtered and yellow crystals suitable for X-ray analysis formed after two weeks on slow evaporation of the solvent at room temperature.

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.
