title: N,N'-Diphenyl-but-2-enediamide.
abstract: In the title compound, C(16)H(14)N(2)O(2), the conformations of the N-H and C=O bonds in the C-NH-CO-CH =CH-CO-NH-C segment are anti to each other. The two C=O bonds are also anti to each other. The two phenyl rings make an inter-planar angle of 41.2 (1)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O hydrogen bonding links the mol-ecules into infinite chains along the a axis.
