M. Yu, X. Chen and Z.-L. Jing

Abstract: The title compound, C₁₄H₁₃N₃O₃, was prepared using 2-hydroxy-3-methoxybenzaldehyde and 4-pyridinecarboxylic acid hydrazide. In the crystal structure, an intramolecular O-HN hydrogen bond [HN = 1.83 (2) Å] appears to stabilize the planar conformation of the molecule, while intermolecular N-HN hydrogen bonds [HN = 2.213 (15) Å] link molecules into extended chains along [001].
