The complete mol­ecule of the title compound, C16H14N4, is generated by crystallographic inversion symmetry. In the crystal, mol­ecules are linked by N—H⋯N hydrogen bonds, generating (001) sheets. Weak aromatic π–π stacking inter­actions [centroid–centroid distances = 3.7383 (13) and 3.7935 (14) Å] are also observed.
