The 19H22INO, contains two independent molecules. Classical intramolecular O—H⋯N hydrogen bonds stabilize the molecular structures. The is stabilized by weak intermolecular C—H⋯π and π–π [centroid–centroid = 3.8622 (18) Å] interactions. In both molecules, the aromatic rings are nearly perpendicular to each other [dihedral angles = 84.26 (17) and 86.69 (15)°].

An ethanolic solution (10 ml) of 2,6-diisopropylaniline (2 mmol) was stirred in a round bottom flask followed by drop wise addition of ethanolic solution (10 ml) of 5-iodosalicylaldehyde (2 mmol). The reaction mixture was then refluxed for 3 h and upon cooling to 273 K. A yellow solid precipitate from the reaction mixture was filtered out, washed with ice cold ethanol and dried over anhydrous CaCl2. Single crystals of good diffraction quality were obtained by the recrystallization of compound from ethanol solution by slow evaporation. Yield: 70 %.
The H atoms were positioned geometrically with C–H = 0.93-0.98Å and O–H = 0.82Å, and allowed to ride on their parent atoms, with Uiso(H) = 1.5 Ueq(O) (or) 1.2Ueq(C) (or) 1.5Ueq(Cmethyl).

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

Schiff base derivatives exhibit antibacterial, antitumor and antitoxic activities (Santos et al., 2001). The asymmetric unit of the title compound I, (Fig. 1), contains two independent molecules. The geometric parameters in I are comparable with the similar reported structures (Lin et al., 2005; Raja et al., 2008). The dihedral angles between the benzene rings (C1-C6) and (C8-C13) & (C20-C25) and (C27-C32) are 84.26 (17)° and 86.69 (15)°. Further, both molecules adopts anti-periplanar (C1-C7-N1-C8 = 177.2 (2)° and C20-C26-N2-C27 = 175.8 (2)°) conformation about C═N bond.
The molecular structure is stabilized by weak intramolecular O–H···N hydrogen bonds and the crystal structure exhibit weak intermolecular C–H···π (Cg2i) (Table 1, Fig. 2) and π–π interactions (Cg1···Cg1ii) with distance 3.8622 (18)Å. Cg1 is the centroid of (C1-C6) ring; Cg2 is the centroid of (C8-C13) ring. Symmetry codes: (i) x-1, y, z; (ii) 1-x, 1-y, -z.
