N′-(5-Bromo-2-hydr­oxy-3-methoxy­benzyl­idene)isonicotinohydrazide

The title compound, C(14)H(12)BrN(3)O(3), was prepared by reaction of 5-bromo-3-methoxy­salicylaldehyde and isonicotinohydrazide in methanol. The mol­ecule is not planar and adopts a trans configuration with respect to the C=N bond. There is an intra­molecular O—H⋯N hydrogen bond in the mol­ecule. The dihedral angle between the benzene and pyridine rings is 12.2 (2)°. In the crystal structure, mol­ecules are linked through inter­molecular N—H⋯N hydrogen bonds, forming chains running along the c-axis direction.
