Abstract: In the structure of the title salt, C12H7N2O2+·CF3SO3-, the cation participates in hydrogen bonding with the dione group of an adjacent cation as well as with the trifluoromethanesulfonate anion. In addition, there is an extensive network of C-H...O interactions between the cations and anions. There are two formula units per asymmetric unit. The crystal studied exhibits inversion twinning.
