The title Schiff base compound, C13H9BrClN3O2·CH4O, was derived from the condensation reaction of 3-bromo-5-chlorosalicylaldehyde with isonicotinohydrazide. The dihedral angle between the benzene and pyridine rings is 5.9 (2)°. In the molecules are linked through N—H⋯O, O—H⋯O, and O—H⋯Br intermolecular hydrogen bonds, forming dimers and chains. There is also an intramolecular O—H⋯N hydrogen bond.

3-Bromo-5-chlorosalicylaldehyde (0.1 mmol, 23.5 mg) and isonicotinohydrazide (0.1 mmol, 13.7 mg) were dissolved in a methanol solution (20 ml). The mixture was stirred at reflux for 10 min to give a clear colourless solution. Colourless block-like crystals of the compound were formed by slow evaporation of the solvent over several days.
H2 was located from a difference Fourier map and refined isotropically, with Uiso restrained to 0.08Å2. Other H atoms were constrained to ideal geometries, with d(C–H) = 0.93–0.96 Å, d(O–H) = 0.82 Å, and with Uiso(H) = 1.2Ueq(C), 1.5Ueq(C14, O1 and O3).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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 author has reported the structures of several Schiff base compounds (Tang, 2006; Tang, 2007a,b,c,d) and, in continuation of work in this area, reports herein the crystal structure of the title new Schiff base compound, (I).
In the title compound (Fig. 1), the dihedral angle between the benzene ring and the pyridine ring is 5.9 (2)°. The torsion angles C1—C7—N1—N2, C7—N1—N2—C8, and N1—N2—C8—C9 are 0.4 (2), 2.3 (2), and 1.9 (2)°, respectively. All the bond lengths are within normal values (Allen et al., 1987).
In the crystal structure of the compound, molecules are linked through N–H···O, O–H···O, and O–H···Br intermolecular hydrogen bonds (Table 1), forming dimers (Fig. 2).
