2-Amino-5-nitro­pyridinium tri­fluoro­acetate

The title salt, C(5)H(6)N(3)O(2) (+)·C(2)F(3)O(2) (−), 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 R (2) (2)(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).
