In the crystal structure of the title compound, C(23)H(20)NO(2) (+)·CF(3)SO(3) (-), the cations form inversion dimers through π-π inter-actions between the acridine ring systems. These dimers are further linked by C-H⋯π inter-actions. The cations and anions are connected by C-H⋯O and C-F⋯π inter-actions. 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.
在标题化合物C(23)H(20)NO(2) (+)·CF(3)SO(3) (-)的晶体结构中，阳离子通过吖啶环系统之间的π-π相互作用形成反演二聚体。这些二聚体通过C-H⋯π相互作用进一步连接。阳离子和阴离子通过C-H⋯O和C-F⋯π相互作用相连。吖啶和苯环系统以20.8 (1)°的二面角取向。羧基相对于吖啶骨架扭转了66.2 (1)°的角度。相邻吖啶单元的平均平面在晶格中是平行的。
