Pyridine-4-carbaldehyde 4-phenylsemicarbazone

Abstract

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...[pi] interactions. The molecular conformation is stabilized by intramolecular N-H...N and C-H...O interactions.
