Abstract

The asymmetric unit of the title salt, C(5)H(6)ClN(2) (+)·C(2)F(3)O(2) (-), contains two independent 2-amino-5-chloro-pyridinium cations and two independent trifluoro-acetate anions. The F atoms of both anions are disordered over two sets of positions, with occupancy ratios of 0.672 (12):0.328 (12) and 0.587 (15):0.413 (15). In the crystal, the cations and anions are linked via N-H⋯O and C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001).
