Abstract: In the title salt, C₆H₉N₂⁺·C₂F₃O₂^-, the F atoms of the anion are disordered over two sets of sites, with refined occupancies in a ratio of 0.505 (17):0.495 (17). In the crystal, cations and anions are linked via N-HO hydrogen bonds, forming R₂²(8) ring motifs. The ionic units are linked into a two-dimensional network parallel to (100) by N-HO and weak C-HO hydrogen bonds. The crystal structure is further stabilized by weak C-HF hydrogen bonds, resulting in a three-dimensional network.
