Abstract: The title compound, C₃₄H₃₅O₂N₃, was synthesized by the reaction of 2-[3,6-bis(diethylamino)-9H-xanthen-9-yl]benzoyl chloride with aniline. In the molecular structure, the dihedral angles between the isoindoline and xanthene planes and between the isoindoline and benzene planes are 86.9 (3) and 47.0 (2)°, respectively. The molecular packing in the crystal structure is stabilized by weak C-HO hydrogen bonding.
