In the title compound, C(16)H(14)N(2)O(2), the conformation about the C=C bond is E, and the two amide groups are effectively orthogonal [the C-N-N-C torsion angle is 104.5 (2)°]. In the crystal structure, the amide groups groups associate via N-H⋯O hydrogen bonding, forming supra-molecular tapes with undulating topology along the c-axis direction.
