In the title compound (systematic name: N,N′-diphenyloctanediamide), C20H24N2O2, the two phenyl rings make an interplanar angle of 76.5 (2)°. The crystal structure is stabilized by intermolecular N—HO hydrogen bonds, which link the molecules into chains running along the b axis. The crystal studied was non-merohedrally twinned, the fractional contribution of the minor twin component being 0.203 (2).
