In the title hydrazone compound, C15H13BrN2O3·CH3OH, the methanol solvate is linked to the benzohydrazide molecule through O—H⋯N and O—H⋯O hydrogen bonds. The benzohydrazide molecule adopts an E configuration about the C=N double bond. The molecule is twisted, with a dihedral angle between the two substituted benzene rings of 35.7 (2)°. In the molecules are linked through intermolecular N—H⋯O and O—H⋯O hydrogen bonds, forming layers parallel to the ac plane.

5-Bromo-2-methoxybenzaldehyde (1.0 mmol, 215.0 mg) and 4-hydroxybenzohydrazide (1.0 mmol, 152.2 mg) were mixed and refluxed in methanol (50 ml). The mixture was stirred for 1 h to give a clear colourless solution. Colourless crystals of (I) were formed by slow evaporation of the solution in air for a few days.
H2 attached to N2 was located in a difference map and refined with N–H distance restraint of 0.90 (1) Å. The other H atoms were positioned geometrically [d(C–H) = 0.93–0.96 Å, d(O–H) = 0.82 Å], and refined using a riding model, with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O and Cmethyl).

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. |

Hydrazone and Schiff base compounds derived from the reaction of aldehydes with hydrazides have been widely investigated both for their crystal structures and biological properties (Khattab et al., 2005; Küçükgüzel et al., 2003; Çukurovalı et al., 2006). In the last few years, a large number of hydrazone derivatives have been reported (Fun et al., 2008; Wei et al., 2009; Khaledi et al., 2008; Yang et al., 2008). However, the hydrazone compounds derived the 5-bromo-2-methoxybenzaldehyde have never been reported. In this paper, the crystal structure of the title new hydrazone compound, (I), derived from the reaction of 5-bromo-2-methoxybenzaldehyde and 4-hydroxybenzohydrazide, is reported.
The molecular structure of (I) is shown as Fig. 1. The compound consists of a hydrazone molecule and a methanol molecule of crystallization. The methanol molecule is linked to the hydrazone molecule through intramolecular O–H···N and O–H···O hydrogen bonds, Table 1. The hydrazone molecule adopts an E configuration about the C═N double bond. The molecule is twisted, with the dihedral angle between the C1—C6 and C10—C15 benzene rings of 35.7 (2)°. All the bond lengths are within normal values (Allen et al., 1987).
In the crystal structure of the compound, molecules are linked through intermolecular N–H···O and O–H···O hydrogen bonds, Table 1, forming layers parallel to the ac plane, as shown in Fig. 2.
