Abstract
The crystal structure of the title compound, C21H15N2O4 +·CF3O3S−, is stabilized by C—H⋯O and C—H⋯F hydrogen bonds, by C—F⋯π, N—O⋯π and S—O⋯π interactions, and by O⋯O [2.70 (4) Å] and O⋯F [2.85 (1) or 2.92 (1) Å] contacts; π–π interactions are also present. In the packing of the molecules, acridine units are either parallel or inclined at an angle of 12.5 (1)°. The nitrophenoxycarbonyl unit is disordered over two position; the site occupancy factors are 0.89 and 0.11.
