title: 5,6-Di-oxo-1,10-phenanthrolin-1-ium trifluoro-methane-sulfonate.
abstract: In the structure of the title salt, C(12)H(7)N(2)O(2) (+)·CF(3)SO(3) (-), the cation participates in hydrogen bonding with the dione group of an adjacent cation as well as with the trifluoro-methane-sulfonate anion. In addition, there is an extensive network of C-H⋯O inter-actions between the cations and anions. There are two formula units per asymmetric unit. The crystal studied exhibits inversion twinning.
