(Received 26 August 2008; accepted 28 October 2008; online 8 November 2008)

There are two molecules in the asymmetric unit of the title compound, C19H21BrClNO, with dihedral angles between the aromatic rings of 70.0 (2) and 81.9 (3)°. The crystal structure is stabilized by inter­molecular C—H⋯π and C—Br⋯π inter­actions. In additional, the stacked mol­ecules exhibit intra­molecular O—H⋯N hydrogen bonds.

Comment top

Schiff base compounds have been of great interest for many years. These compounds play an important role in the development of coordination chemistry related to catalysis and enzymatic reactions, magnetism and molecular architectures (Pu, 2008). As a part of our ongoing investigation in this field we have determined the crystal structure of the title compound, (I).

Fig.1 shows the asymmetric unit consisting of two molecules of (I) viz. unit A and unit B. The two crystallographically independent molecules have the same geometrical parameters within the precision of the experiments. The bond lengths and angles in (I) are comparable to the corresponding values in the related structure, 2-Bezyliminomethyl-6-bromo-4-chloro-phenol (Pu, 2008). Like other Schiff base compounds containing salicylidene (Figuet et al., 2001; Kennedy & Reglinski, 2001; Thamotharan et al., 2003) the hydroxyl groups form intramolecular hydrogen bonds with the N atoms, thereby completing six-membered rings (Fig. 2). The molecular packing is stabilized by intermolecular C—H···π and C—Br···π interactions, with a C28—H28A···Cg1i separation of 2.96 Å and a C16—Br1···Cg2i separation of 3.532 (5) Å (Fig. 2 and Table 1; Cg1 and Cg2 are the centroids of the C14-C19 and C33-C38 benzene rings, respectively, symmetry code as in Fig. 2). In addition, the molecular packing is further stabilized by two intramolecular O—H···N hydrogen bonds (Table 1).

Experimental top

The title compound was synthesized by refluxing an ethanol solution (20 ml) of 5-bromo-3-chloro-2-hydroxybenzaldehyde (1.72 g, 10 mmol) and 2,6-diisopropylaniline (1.72 g, 10 mmol), at 80°C for 2 h. Upon cooling to 0°C, a yellow solid crystalline product was obtained. The precipitate was filtered off and washed with cold ethanol. Single crystal of good diffraction quality was obtained by the recrystallization of compound with ethanol solution by slow evaporation method.

Refinement top

All H atoms were fixed geometrically and allowed to ride on their parent C atoms, with C—H distances fixed in the range (0.82–0.97)Å with Uiso(H)= 1.5Ueq(methyl H) and 1.2Ueq(for other H atoms).

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.
