Abstract: 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).
