Abstract

In the crystal structure of the title compound, C21H15FNO2 +·CF3SO3 −, the cations form inversion dimers through C—H⋯O, C—F⋯π and π–π interactions. These dimers are further linked by π–π interactions. The cations and anions are connected through C—H⋯O, C—F⋯π and S—O⋯π interactions. The acridine and benzene ring systems are oriented at a dihedral angle of 74.1 (1)°. The carboxylate group is twisted at an angle of 4.4 (1)° relative to the acridine skeleton. The mean planes of the adjacent acridine moieties are parallel or inclined at an angle of 55.4 (1)° in the crystal structure.
