title: 3',6'-Bis(diethyl-amino)-2-phenyl-spiro[isoindoline-1,9'-xanthen]-3-one.
abstract: The title compound, C(34)H(35)O(2)N(3), was synthesized by the reaction of 2-[3,6-bis-(diethyl-amino)-9H-xanthen-9-yl]benzoyl chloride with aniline. In the mol-ecular 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 mol-ecular packing in the crystal structure is stabilized by weak C-H⋯O hydrogen bonding.
