✦ Synopsis


The title compound, also known as 2-amino-5-[4-(octylamino)phenyl]tropone, C 21 H 28 N 2 O, contains two crystallographically independent molecules in the asymmetric unit. The NH 2 group of the 2-aminotropone unit and the NH group of the aminobenzene unit participate in intermolecular hydrogen bonding with the O atoms of neighbouring molecules. An intermolecularinteraction is observed in the crystal structure.
