N-{1,2-Bis(pyridin-3-yl)-2-[(E)-(pyridin-3-yl)methylideneamino]ethyl} nicotinamide

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.
