Abstract The structure of 4-N-benzylaminocoumarin (C16H13NO2) has been determined by X-ray diffraction and the Ft-ir,1H- and13C-nmr spectra of the compound were recorded. Crystals of the compound are monoclinic, space group P21/c, with cell dimensiona=8.077(2),b=14.598(4),c=10.890(3) Å, and β=97.76(3)°. The Ft-ir and nmr spectra indicate that the nitrogen atom is in the amino form in solution. The crystal structure is consistent with this observation, but the C(3)−C(4) double bond is clearly delocalized to include the lone pair on the nitrogen atom.
