An ethanolic solution (10 ml) of 2,6-diisopropylaniline [2 mmol] was magnetically stirred in a round bottom flask followed by drop wise addition of ethanolic solution (10 ml) of 5-chlorosalicylaldehyde [2 mmol]. The reaction mixture was then refluxed for 3 h and upon cooling to 273 K, a yellow solid precipitated from the reaction mixture. The solid which separated out was filtered, washed with ice cold ethanol and dried over anhydrous CaCl2. Single crystals of good diffraction quality were obtained by recrystallization of the compound from an ethanol solution by the slow evaporation method.Yield: 70 %.
H atoms were positioned geometrically with C—H = 0.93–0.97 Å and O–H = 0.82 Å and allowed to ride on their parent atoms, with Uiso(H) = 1.5 Ueq(O) or 1.2Ueq(C) or 1.5Ueq(Cmethyl).

Schiff base derivatives are found to exhibit important pharmacological properties, such as antibacterial, antitumor and antitoxic activities (Santos et al., 2001).
The asymmetric unit of the title compound (I) (Fig. 1) contains two molecules. The geometric parameters in (I) are comparable with the similar reported structures (Raja et al., 2008; Lin et al., 2005). The dihedral angles between the aromatic rings (C1-C6) and (C14-C19) & (C21-C26) and (C33-C38) are 76.45 (9) and 74.69 (9)°, respectively. In the asymmetric unit of (I), both molecules adopt an anti-periplanar conformation [C14-C13-N1-C1 = 176.31 (15)° and C33-C32-N2-C20 = -176.22 (15)°] about the C=N bond.
The molecular structure is stabilized by weak intramolecular O-H···N hydrogen bonds and C-H···π interactions (Table 1). The crystal structure is stabilized by a weak intermolecular C-H···π interaction (Table 1).
