(2E)-2-Hydroxyimino-N′-[(E)-2-pyridylmethylene]propanohydrazide

Abstract

In the title compound, C9H10N4O2, the pyridine ring is twisted by 16.5 (1)° from the mean plane defined by the remaining non-H atoms. An intramolecular N—H...N interaction is present. In the crystal, intermolecular O—H...N and N—H...O hydrogen bonds link molecules into layers parallel to the bc plane. The crystal packing exhibits π–π interactions indicated by the short distance of 3.649 (1) Å between the centroids of the pyridine rings of neighbouring molecules.
