Acridinium 2-hydroxybenzoate
Abstract
In the title compound, C13H10N+·C7H5O3− or (acrH)+(Hsal)−, the asymmetric unit contains one acridinium cation and one salicylate anion. The acridinium N atom is protonated and the carboxylic 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 intermolecular N—H...O, O—H...O and C—H...O hydrogen bonds. C—H...π interactions are also present.
