Abstract:
In the crystal structure of the title compound, C(27)H(20)NO(2) (+)·CF(3)SO(3) (-), the cations form inversion dimers through π-π inter-actions between the acridine ring systems [centroid-centroid distances = 3.668 (2)-3.994 (2) Å]. These dimers are further linked by C-H⋯O and C-H⋯π inter-actions. The cation and the anion are connected by C-H⋯O inter-actions. The mean plane of the acridine ring system makes dihedral angles of 10.6 (1) and 82.5 (1)°, respectively, with the adjacent phenyl ring and the carb-oxy group. The two phenyl rings of the biphenyl group are oriented at 42.9 (1)°.
