3′,6′-Bis(diethylamino)-2-phenylspiro[isoindoline-1,9′-xanthen]-3-one

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—H...O hydrogen bonding.
