2-Dicyanomethylene-5,6-dimethyl-1,2-dihydropyridine-3-carbonitrile

The title compound, C₁₁H₈N₄, exists as the NH tautomer (a 1,2-dihydropyridine) in the solid state, although the bond-length differences in the ring are minimal (thus implying delocalized multiple bonding). Molecules are linked in pairs by N—H...N hydrogen bonds over inversion centres.
