S1. Comment

The chemistry of aroylhydrazones continues to attract much attention due to their coordination ability to metal ions (Singh et al., 1982; Salem, 1998) and their biological activity (Singh et al., 1982; Carcelli et al., 1995). As an extension of work on the structural characterization of aroylhydrazone derivatives, the title compound, (I), was synthesized and its crystal structure is reported here.

The title molecule displays a trans conformation with respect to the C7=O2 double bond (Fig. 1). The crystal structure is stabilized by intramolecular O—H···O and intermolecular C—H···O hydrogen bonding and C-H···π interactions (Table 1. and Fig. 2).

Related literature

For the ability of aroylhydrazones to coordinate to metal ions and their biological activity, see: Singh et al. (1982); Salem (1998); Carcelli et al. (1995). Cg1 is the centroid of the C8–C13 ring.

S2. Experimental

The benzoyl chloride (0.01 mol, 1.4057 g) and the 4-bromophenol, heated up in the oil bath, the reaction mixture was refluxed for 6 h with stirring. Then anhydrous aluminium trichloride (3 mol, 1:3) was added, the backflow agitation responds for 4 h (yield 80%). The compound (2.0 mmol, 0.67 g) was dissolved in dimethylformamide (30 ml) and kept at room temperature for 30 d to obtain brown single crystals suitable for X-ray diffraction.

S3. Refinement

All H atoms were positioned geometrically and treated as riding on their parent atoms,with C—H(aromatic) = 0.93 Å, O—H = 0.82 Å, and with U_iso(H) = 1.2U_eq(C) and 1.5U_eq(O).

Special details

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.
