1,10-Phenanthrolinium 2,3,4,5,6-penta-fluoro-benzoate-2,3,4,5,6-penta-fluoro-benzoic acid (1/2).

In the title compound, C(12)H(9)N(2) (+)·C(7)F(5)O(2) (-)·2C(7)HF(5)O(2), the cation and anion are linked by an N-H⋯O hydrogen bond. The neutral mol-ecules bond to the anion via O-H⋯O hydrogen bonds to form associations of one cation, one anion and two neutral mol-ecules. Inter-molecular C-H⋯O, C-H⋯F, F⋯F [shortest contact = 2.768 (8) Å], F⋯π [shortest contact = 3.148 (13) Å] and π-π [shortest centroid-centroid separation = 3.689 (5) Å] inter-actions further link the components to form a three-dimensional network.
