title: Pyridine-4-carbaldehyde 4-phenylsemicarbazone.
abstract: In the title compound, C(13)H(12)N(4)O, the semicarbazone fragment links a benzene and a pyridine ring in the structure. The crystal packing is stabilized by strong inter-molecular N-H⋯O hydrogen bonds, which connect two mol-ecules to form a synthon unit, and by N-H⋯N hydrogen bonds and weak C-H⋯π inter-actions. The mol-ecular conformation is stabil-ized by intra-molecular N-H⋯N and C-H⋯O inter-actions.
