The title compound, 2,3-benzo-7,10,13-trioxa1,4-diaza-2-pentadecene, C14H22N2O3, is a derivative of benzo-15-crown-5 in which the two O atoms flanking the aromatic ring are replaced by NH groups. Except for the rigidly near-planar OC6H4O segment, the macrocycle contains gauche C-C and a mixture of gauche and anti C-O and C-N linkages.
