N '-(2-Hydroxy-4-methoxybenzylidene)isonicotinohydrazide

The title compound, C(14)H(13)N(3)O(3), was synthesized by the condensation reaction of 2-hydroxy-4-methoxybenzaldehyde with isonicotinohydrazide in a methanol solution. The molecule of the compound displays a trans configuration with respect to the C = N and C-N bonds. The dihedral angle between the benzene and the pyridine rings is 27.3 (2)degrees. In the crystal, molecules are linked by N-H center dot center dot center dot N interactions into zigzag chains with graph-set notation C(7) along [010]. An intramolecular O-H center dot center dot center dot N hydrogen bond is observed.
