The compound was prepared by the reaction of equimolar quantities (1.0 mmol each) of 3-bromo-5-chloro-2-hydroxybenzaldehyde and 2-chlorobenzohydrazide in methanol (100 ml) for 2 h at room temperature. The solution was kept in air for a week, forming yellow blocks of (I).
The N-bound H atom was located in a difference Fourier map and was refined with an N–H distance restraint of 0.90 (1) Å. Other H atoms were placed in calculated positions (C–H = 0.93–0.96 Å, O–H = 0.82 Å) and refined using a riding model with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O and C15).

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, the crystal structures of hydrazone compounds have been widely studied (Fun et al., 2008; Ali et al., 2007; Zhi & Yang, 2007). In this paper, the structure of the title compound, (I), is described.
The title compound consists of a hydrazone molecule and a methanol molecule (Fig. 1). The dihedral angle between the two benzene rings is 49.2 (2)°. The methanol molecule is linked to the hydrazone molecule through an intramolecular O–H···O hydrogen bond (Table 1).
