Abstract: In the title compound, C24H20N6O, the pyridin-3-yl groups on the ethyl­ene fragment are found in a trans conformation with a C(py)-C(e)-C(e)-C(py) (py = pyridine, e = ethylene) torsion angle of 179.2 (3)°. The dihedral angle between the pyridine rings is 3.5 (1)°. In the crystal, N-H...N and C-H...O=C inter­actions form a layer arrangement parallel to the bc plane. The compound displays disorder of the ethyl­ene fragment over two positions with an occupancy ratio of 0.676 (7) to 0.324 (7) that extends into the amide section of the nicotinamide moiety.
