1,2-Bis(2-pyridylformimidoyl)hydrazine

The title compound, C₁₂H₁₂N₆, is the minor trans product of the preparation of a dihydrotetrazine. Extensive electron delocalization is shown by the planarity of the molecule, except for one pyridyl group twisted out of plane by only 14.1 (1)°. The C=N–N=C fragment has a C—N distance of 1.297 (2) Å and an N—N distance of 1.404 (2) Å. All other C—N distances are close to 1.34 Å, typical of C[pdbond]N bonds. The NH₂ groups form hydrogen bonds to pyridyl and hydrazine N atoms of adjacent molecules.
