Pyridine-4-carbaldehyde 4-phenylsemicarbazone

In the title compound, C13H12N4O, the semicarbazone fragment links a benzene and a pyridine ring in the structure. The crystal packing is stabilized by strong intermolecular N—H...O hydrogen bonds, which connect two molecules to form a synthon unit, and by N—H...N hydrogen bonds and weak C—H...π interactions. The molecular conformation is stabilized by intramolecular N—H...N and C—H...O interactions.
