In the cation of the title salt, the central thiazolidine ring adopts an envelope conformation. In the crystal N-H ··· Br hydrogen bonds link the components into a bi-dimensional network with the cations and anions stacked parallel to plane (101). The molecular structure shows several positional disorders over -CF3 and thiazolidine fragments and these were modeled. The weak intermolecular interactions in the crystal structure are mainly constituted by H ··· F, H ··· π and H ··· Br. Hirshfeld surface analysis were used to verify the contributions of the different intermolecular interactions.
