In the title mol-ecule, C(12)H(12)N(6), the dihedral angles between the pyridine rings and the central dimethan-imine-hydrazine group are 0.30 (3) and 13.94 (3)°. Two intra-molecular N-H⋯N hydrogen bonds stabilize the planar conformation of one pyridine ring with respect to its hydrazine-residue neighbour, whereas the other pyridine ring and an N-bonded H atom are rotated out of the plane and l...
