Crystal structure and Hirshfeld surface analysis of (E)-3-[(2,3-di­chloro­benzyl­idene)amino]-5-phenyl­thia­zolidin-2-iminium bromide

In the cation of the title salt, C(16)H(14)Cl(2)N(3)S(+)·Br(−), the central thia­zolidine ring adopts an envelope conformation. The phenyl ring is disordered over two sites with a refined occupancy ratio of 0.541 (9):0.459 (9). In the crystal, C—H⋯Br and N—H⋯Br hydrogen bonds link the components into a three-dimensional network with the cations and anions stacked along the b-axis direction. Weak C—H⋯π inter­actions, which only involve the minor disorder component of the ring, also contribute to the mol­ecular packing. In addition, there are also inversion-related Cl⋯Cl halogen bonds and C—Cl⋯π (ring) contacts. A Hirshfeld surface analysis was conducted to verify the contributions of the different inter­molecular inter­actions.
