(E)-N'-(5-Chloro-2-hydroxybenzylidene)-3,5-dihydroxybenzohydrazide monohydrate

Abstract top

In the title compound, C14H11ClN2O4·H2O, the dihedral angle between the two benzene rings is 8.5 (2)° and an intramolecular O-H...N hydrogen bond is observed in the Schiff base molecule. In the crystal structure, the water molecule accepts an N-H...O hydrogen bond and makes O-H...O hydrogen bonds to two further Schiff base molecules. Further intermolecular O-H...O hydrogen bonds lead to the formation of layers parallel to the bc plane.

Comment top

Schiff base compounds can be easily synthesized from the reaction of aldehydes with primary amines (Herrick et al., 2008; Suresh et al., 2007). These compounds show interesting biological activities, especially antimicrobial activities (Bhandari et al., 2008; Sinha et al., 2008). In this paper, the crystal structure of the title compound, (I), containing a new Schiff base compound derived from the condensation reaction of 5-chlorosalicylaldehyde with 3,5-dihydroxybenzoic acid hydrazide is reported.

The Schiff base molecule of (I) displays a trans configuration with respect to the C=N and C—N bonds (Fig. 1). All the bond lengths are within normal ranges (Allen et al., 1987), and are comparable to those in the related compound 3,5-dihydroxy-N'-(2-hydroxybenzylidene) benzohydrazide monohydrate (Jiang et al., 2008). The Schiff base molecule is nearly planar, the dihedral angle between the two benzene rings is 8.5 (2)°. An intramolecular O—H···N hydrogen bond is observed. In the crystal structure the water molecule links three symmetry related molecules through O—H···O and O—H···N hydrogen bonds (Table 1). Together with two further intermolecular O—H···O hydrogen bonds, layers parallel to the bc plane are formed (Fig. 2).

Experimental top

5-Chlorosalicylaldehyde (0.1 mmol, 15.6 mg) and 3,5-dihydroxybenzoic acid hydrazide (0.1 mmol, 16.8 mg) were dissolved in a 95% ethanol solution (10 ml). The mixture was stirred at room temperature to give a clear solution. Light yellow blocks of (I) were formed by gradual evaporation of the solvent over a period of nine days at room temperature.

Refinement top

All H atoms were placed in geometrically idealized positions (C—H = 0.93 Å, O—H = 0.82–0.85 Å and N—H = 0.86 Å) and refined as riding with Uiso(H) = 1.2Ueq(C,N) or 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.
