2-Amino-5-nitro­pyridinium tri­fluoro­acetate

The title salt, C₅H₆N₃O₂⁺·C₂F₃O₂⁻, crystallizes with two cations and two anions in the asymmetric unit. In the crystal, the acetate and pyridine groups are linked by a pair of N—H...O hydrogen bonds, forming loops described by the graph-set motif R₂²(8). These loops are linked via N—H...O hydrogen bonds, forming chains along [001]. The chains are in turn linked by C—H...O and C—H...F hydrogen bonds, generating a three-dimensional supra­molecular network. In both anions, the O and F atoms are disordered over two sites, with occupancy ratios of 0.852 (3):0.148 (3) and 0.851 (3):0.149 (3).
