Abstract
The title compound, C12H9ClN4O, was prepared by the reaction of pyrazine‐2‐carboxylic acid hydrazide and 2‐chlorobenzaldehyde in methanol. In the crystal structure, there are intramolecular N—H⋯N and intermolecular C—H⋯O hydrogen bonds. Weak π–π stacking interactions are also observed between two parallel molecules.
