Abstract

In the crystal structure of the title compound, C(23)H(20)NO(4) (+)·CF(3)SO(3) (-), the cations are linked through C-H⋯O, C-H⋯π and π-π inter-actions [centroid-centroid distances = 3.641 (2) and 3.885 (2) Å]. The cation and the anion are held together by C-H⋯O and S-O⋯π inter-actions. The acridine ring system and the benzene ring in the cation are oriented at a dihedral angle of 8.7 (1)°. The carb-oxy group is twisted at an angle of 83.2 (1)° relative to the acridine skeleton.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Symmetry code: (ii) . Notes: Cg1, Cg2 and Cg4 are the centroids of the C9/N10/C11–C14, C1–C4/C11/C12 and C18–C23 rings, respectively. CgI⋯CgJ is the distance between ring centroids. The dihedral angle is that between the planes of the rings I and J. CgI Perp and CgJ Perp are the perpendicular distances of CgI from ring J and of CgJ from ring I, respectively. CgI Offset and CgJ Offset are the distances between CgI and the perpendicular projection of CgJ on ring I, and between CgJ and the perpendicular projection of CgI on ring J, respectively.
