RESUMO
In the title compound, C24H20N6O, the pyridin-3-yl groups on the ethyl-ene fragment are found in a trans conformation with a C(py)-C(e)-C(e)-C(py) (py = pyridine, e = ethylene) torsion angle of 179.2â (3)°. The dihedral angle between the pyridine rings is 3.5â (1)°. In the crystal, N-Hâ¯N and C-Hâ¯O=C inter-actions form a layer arrangement parallel to the bc plane. The compound displays disorder of the ethyl-ene fragment over two positions with an occupancy ratio of 0.676â (7) to 0.324â (7) that extends into the amide section of the nicotinamide moiety.
RESUMO
In the solid state, the structure of the title compound, C(18)H(15)N(5), is stabilized by weak C-Hâ¯N interactions. Mol-ecules are arranged in layers parallel to the bc plane forming an inter-esting supra-molecular structure.
