Abstract top

In the title compound, C14H10Cl2N2O3, the dihedral angle between the two benzene rings is 5.1 (2)°. The molecule adopts an E configuration with respect to the C=N bond and an intramolecular O-H...N interaction is present. In the crystal structure, molecules are linked through intermolecular N-H...O and O-H...O hydrogen bonds.

Comment top

The Schiff base compounds show excellent biological properties (Jeewoth et al., 1999; Ren et al., 2002; Eltayeb et al., 2008; Sinha et al., 2008). Moreover, the Schiff base compounds have been widely used as versatile ligands in coordination chemistry (Shivakumar et al., 2008; Prabhakaran et al., 2006; Dhar et al., 2005). We report here the crystal structure of the title compound. In the title compound, Fig. 1, the dihedral angle between the two benzene rings is 5.1 (2)°. All the bond lengths are within normal values (Allen et al., 1987) and comparable to those in other similar compounds (Cui et al., 2007; Jing et al., 2007; Ma et al., 2008; Salhin et al., 2007; Lin et al., 2007; Alhadi et al., 2008; Xue et al., 2008; Wang et al., 2008; Lu, 2008; Diao et al., 2008; Qiu, 2009; Mohd Lair et al., 2009a,b). —H···N OIn the crystal structure, molecules are linked through intermolecular N–H···O and O–H···O hydrogen bonds (Table 1), Fig. 2.

Experimental top

All the starting materials were obtained with AR grade from Lancaster. 3,5-Dichloro-2-hydroxybenzaldehyde (1.0 mmol, 192.2 mg) and 4-hydroxybenzohydrazide (1.0 mmol, 152.2 mg) were refluxed in 30 ml methanol solution for 30 min giving a clear yellow solution. Yellow block-shaped single crystals of the compound were obtained by slow evaporation of the solution for a week at room temperature.

Refinement top

H2 was located from a difference Fourier map and refined isotropically, with the N–H distance restrained to 0.90 (1) Å, and with Uiso restrained to 0.08 Å2. Other H atoms were constrained to ideal geometries, with d(C–H) = 0.93 Å, d(O–H) = 0.82 Å, and with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O).

Special details top

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.
