9-Benzyl-10-methylacridinium trifluoromethanesulfonate

Abstract

In the crystal structure of the title compound, C21H18N+·CF3OS3−, 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, C—F...π and S—O...π interactions. The acridine and benzene ring systems are oriented at a dihedral angle of 76.8 (1)°with respect to each other. The acridine moieties are either parallel or inclined at an angle of 62.4 (1)° in the crystal structure.
