title: Acridinium 2-hy-droxy-benzoate.
abstract: In the title compound, C(13)H(10)N(+)·C(7)H(5)O(3) (-) or (acrH)(+)(Hsal)(-), the asymmetric unit contains one acridinium cation and one salicylate anion. The acridinium N atom is protonated and the carb-oxy-lic acid group of salicylic acid is deprotonated. Both moieties are planar, with an r.m.s. deviation of 0.0127 Å for the acr cation and 0.0235 ° for the sal anion. They are aligned with a dihedral angle of 71.68 (3)° between them. The crystal structure is stabilized by a network of inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. C-H⋯π inter-actions are also present.
