In the title compound, C14H10BrN3O4·CH4O, the benzohydrazide molecule is nearly planar [maximum deviation = 0.110 (2) Å]. The mean planes of the two benzene rings make a dihedral angle of 8.4 (3)°. In the benzohydrazide molecule, there is an intramolecular O—H⋯N hydrogen bond and the NH group is hydrogen bonded to the methanol solvent molecule. In the crystal, intermolecular O—H⋯O hydrogen bonds involving the methanol solvent molecule link the benzohydrazide molecules to form chains which propagate along the a axis.

To a methanol solution (20 ml) of 5-bromosalicylaldehyde (0.1 mmol, 20.1 mg) and 4-nitrobenzohydrazide (0.1 mmol, 18.1 mg), a few drops of acetic acid were added. The mixture was refluxed for 1 h and then cooled to room temperature. The white crystalline solid was collected by filtration, washed with cold methanol and dried in air. Single crystals, suitable for X-ray diffraction, were obtained by slow evaporation of a methanol solution of the product in air.
The NH H-atom was located in a difference Fourier map and was refined with a distance restraint, N-H = 0.90 (1) Å, and Uiso(H) = 0.08 Å2. The OH and C-bound H atoms were positioned geometrically and refined using a riding model: O-H = 0.82 Å, C—H = 0.93 and 0.96 Å, for CH and CH3 H-atoms, respectively, with Uiso(H) = k × Ueq(O,C) where k = 1.5 for OH and CH3 H-atoms and k = 1.2 for all other 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. |

Benzohydrazide compounds are well known for their biological activities (El-Sayed et al., 2011; Horiuchi et al., 2009). In addition, benzohydrazide compounds have also been used as versatile ligands in coordination chemistry (El-Dissouky et al., 2010, Zhang et al., 2010). As a contribution to a structural study on hydrazone compounds, we present here the crystal structure of the title compound, that was obtained as the product of the reaction of 5-bromosalicylaldehyde with 4-nitrobenzohydrazide in methanol.
The title compound contains a benzohydrazide molecule and a methanol solvent molecule of crystallization (Fig. 1). In the benzohydrazide molecule there is an intramolecular O-H···N hydrogen bond and NH group is hydrogen bonded to the methanol solvate molecule. The bond distances (Allen et al., 1987) and angles are within normal ranges and agree well with the corresponding bond distances and angles reported in closely related compounds (Suleiman Gwaram et al., 2010; Dai & Mao, 2010; Ban, 2010). The benzohydrazide molecule is nearly planar [maximum deviation of 0.110 (2) Å], with the mean planes of the two benzene rings making a dihedral angle of 8.4 (3)°.
In the crystal, intermolecular O—H···O hydrogen bonds involving the methanol solvate molecule link the benzohydrazide molecules to form chains which propagate along along the a axis direction (Table 1, Fig. 2).
