In the title compound, C14H9Cl2N3O4·CH4O, the dihedral angle between the two benzene rings in the hydrazone molecule is 6.3 (3)°. An intramolecular N—H⋯O hydrogen bond stabilizes the molecular conformation. In the crystal, centrosymmetrically related molecules are linked through intermolecular O—H⋯O and N—H⋯O hydrogen bonds.

3,5-Dichlorosalicylaldehyde (0.191 g, 1 mmol) and 4-nitrobenzohydrazide (0.181 g, 1 mmol) were dissolved in 30 ml absolute methanol. The mixture was stirred at reflux for 10 min, and cooled to room temperature. The clear yellow solution was left to slowly evaporate in air for a week, yielding yellow needle crystals of the title compound suitable for X-ray analysis.
The H2 atom attached to N2 was located in a difference Fourier map and refined isotropically, with the N—H distance restrained to 0.90 (1) Å, and with Uiso fixed at 0.08 Å2. The remaining H atoms were positioned geometrically and refined using the riding-model approximation, with C—H = 0.93–0.96 Å, O—H = 0.82 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C, O) for methyl and hydroxy H atoms.

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. |

In recent years, considerable interest has been focused on the preparation and biological properties of hydrazone compounds (Rasras et al., 2010; Fan et al., 2010; Ajani et al., 2010; Avaji et al., 2009). The crystal structures of a number of hydrazone compounds have been reported (Khaledi et al., 2010; Han et al., 2010; Hussain et al., 2010; Ji & Lu, 2010). The author reports in this paper the title new hydrazone compound.
The asymmetric unit of the title compound (Fig. 1) consists of a hydrazone molecule and a methanol molecule. The dihedral angle between the C1—C6 and C9—C14 benzene rings is 6.3 (3)°. There is an intramolecular O—H···N hydrogen bond (Table 1) stabilizing the conformation of the hydrazone molecule. All bond lengths are within normal values (Allen et al., 1987), and are comparable with those in the similar hydrazone compounds as cited above. In the crystal structure (Fig. 2), centrosymmetrically related molecules are linked through intermolecular O—H···O and N—H···O hydrogen bonds (Table 1).
