The title Schiff base compound, C19H25N3O, is approximately planar, with a dihedral angle of 9.03 (13)° between the planes of the aromatic rings, and has an E conformation about the N=C bond. The molecular structure is stabilized by an intramolecular O—H⋯N hydrogen bond, with an S(6) ring motif. In the crystal, molecules are linked by C—H⋯π interactions, forming sheets parallel to the bc plane.

Schiff base derivatives are known to exhibit antimicrobial (Savaliya et al., 2010) and antibacterial (Xu et al., 2012) activities. Herein we report on the synthesis and the
of a new Schiff base compound.The molecular structure of the title compound is illustrated in Fg. 1. The geometric parameters are comparable to those reported for similar structures (Manvizhi et al., 2011; Thirugnanasundar et al., 2011). The dihedral angle between the benzene rings (C3—C8) and (C10—C15) is 9.03 (13)°. The molecular structure is stabilized by an intramolecular O—H···N hydrogen bond (Table 1 and Fig. 1).
In the crystal, molecules are linked by C—H···π interactions forming sheets parallel to the bc plane (Table 1 and Fig. 2).
To an ethanol solution (10 ml) of 5-(diethylamino)-2-hydroxybenzaldehyde (96.5 mg, 0.5 mol) was added N1,N1-dimethylbenzene-1,4-diamine (68 mg, 0.5 mol). The mixture was stirred and 2 to 3 drops of glacial acetic acid were added. Stirring was continued for 30 mins and then the reaction mixture was refluxed for 2 h. On completion of the reaction, monitored by TLC, the mixture was allowed to cool to room temperature and the solid yellow precipitate that formed was filtered, dried, and recrystallized from DMF, giving colourless block-like crystals.
Crystal data, data collection and structure
details are summarized in Table 2. H atoms were positioned geometrically and refined using riding model: O—H = 0.82 Å, C—H = 0.93 - 0.97 Å with Uiso(H) = 1.5Ueq(O,C) for the hydroxyl and methyl H atoms and 1.2Ueq(C) for other H atoms. The components of the anisotropic displacement parameters of the atoms in bonds N3—C16, N3—C18 and N1—C2 were restrained to be equal within an effective standard deviation of 0.001 using the DELU command, and the C16—C17 bond distance was restrained to 1.54 (1) Å.Data collection: APEX2 (Bruker, 2004); cell

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. |
