✦ Synopsis

The crystal structure of the title compound, C~7~H~7~F~3~N^+^·C~8~H~3~Cl~2~O~4~
^−^, is stabilized by five N—H...O, one O—H...O, two C—H...O and three C—H...X (X = F, Cl) hydrogen bonds. Intramolecular O—H...O and C—H...X hydrogen bonds generate edge-fused [S(7)R

^4^(24)S(7)R
~2~
^2^(10)S(7)R

^4^(24)S(7)] motifs. The cations and anions are linked to each other by C—H...O hydrogen bonds, forming a chain along the c axis. This chain and the other hydrogen bonds form [R
