Abstract: In the crystal structure of the title compound, C21H15BrNO2+·CF3SO3-, the cations form inversion dimers through - interactions between the acridine ring systems. These dimers are further linked by C-H and C-Br interactions. The cations and anions are connected by multidirectional C-HO and C-F interactions. The acridine and benzene ring systems are oriented at 10.8 (1)°. The carboxyl group is twisted at an angle of 85.2 (1)° relative to the acridine skeleton. The mean planes of adjacent acridine units are parallel or almost parallel [inclined at an angle of 1.4 (1)°] in the crystal structure.
