چکیده
In the mol-ecular structure of the title compound, C(15)H(13)ClNO(2) (+)·CF(3)SO(3) (-), the meth-oxy groups are nearly coplanar with the acridine ring system, making dihedral angles of 0.4 (2) and 5.1 (2)°. Multidirectional π-π contacts between acridine units are observed in the crystal structure. N-H⋯O and C-H⋯O hydrogen bonds link cations and anions, forming a layer structure.
