title: N'-(2-Hydr-oxy-4-methoxy-benzyl-idene)isonicotinohydrazide.
abstract: The title compound, C(14)H(13)N(3)O(3), was synthesized by the condensation reaction of 2-hydr-oxy-4-methoxy-benzaldehyde with isonicotinohydrazide in a methanol solution. The mol-ecule 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)°. In the crystal, mol-ecules are linked by N-H⋯N inter-actions into zigzag chains with graph-set notation C(7) along [010]. An intra-molecular O-H⋯N hydrogen bond is observed.
