In the title compound, C14H10ClN3O4·CH3OH, the dihedral angle between the two benzene rings is 33.9 (2)°. In the crystal structure, the methanol solvent molecules are linked to the Schiff base molecules through intermolecular N-H
O and O-H
O hydrogen bonds. Molecules are further linked through intermolecular O-H
O and O-H
N hydrogen bonds, forming chains running along the b axis.
2-Chloro-5-nitrobenzaldehyde (1.0 mmol, 167.1 mg) and 3-hydroxybenzohydrazide (1.0 mmol, 152.1 mg) were dissolved in methanol (30 ml). The mixture was stirred at reflux for 30 min to give a colourless solution. After keeping the solution in air for a few days, colourless block-shaped crystals were formed.
H3B was located in a difference Fourier map and refined isotropically, with Uiso(H) fixed at 0.08 Å2. Other H atoms were positioned geometrically and refined using a riding model with O–H = 0.92 Å, C–H = 0.93-0.96 Å, and with Uiso(H) = 1.2 or 1.5Ueq(C, O).

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. |

Recently, we have reported two metal complexes with Schiff base ligands (Zhou & Tang, 2007; Zhou & Xiao, 2007). We report herein the crystal structure of the title Schiff base compound (Fig. 1).
The title compound consists of a Schiff base molecule and a methanol molecule of crystallization. The dihedral angle between the two benzene rings is 33.9 (2)°. All bond lengths are comparable to those found in similar compounds (Ali et al., 2007; Nie, 2008; He, 2008; Butcher et al., 2007; Jing & Yu, 2007). In the crystal structure, the methanol molecules are linked to the Schiff base molecules through intermolecular N–H···O and O–H···O hydrogen bonds (Table 1). Molecules are further linked through intermolecular O—H···O and O—H···N hydrogen bonds to form chains running along the b axis (Fig. 2).
