Abstract: In the crystal structure of the title compound, C₁₄H₁₂NS⁺·CF₃SO₃^-, N-HO hydrogen bonds link cations and anions into ion pairs. Inversely oriented ion pairs form stacks through multidirectional - interactions among the acridine units. The crystal structure features a network of C-HO interactions among stacks and also long-range electrostatic interactions among ions. In the packing of the molecules, the acridine units are nearly parallel in stacks or inclined at an angle of 33.07 (2)° in the four adjacent stacks with which they interact via weak C-HO interactions. The methylsulfanyl group is twisted through an angle of 60.53 (2)° with respect to the acridine ring.
