Abstract: The title compound {alternative name: 1,3-bis(di-2-pyridylmethylene)amino]urea}, C₂₃H₁₈N₈O, adopts an EE configuration about the hydrazine bonds and exists in the ketone form. Intramolecular N-HN hydrogen bonds are observed. Molecules translated by one unit cell along the a-axis direction are linked by C-HO hydrogen-bonding interactions, forming a chain. In addition, C-H and - interactions are observed.
