Abstract
In the crystal structure of the title compound, C23H20NO2 +·CF3SO3 −, the cations form inversion dimers through π–π interactions between the acridine ring systems. These dimers are further linked by C—H⋯π interactions. The cations and anions are connected by C—H⋯O and C—F⋯π interactions. The acridine and benzene ring systems are oriented at a dihedral angle of 20.8 (1)°. The carboxyl group is twisted at an angle of 66.2 (1)° relative to the acridine skeleton. The mean planes of adjacent acridine units are parallel in the lattice.
