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

Abstract

In the cation of the title salt, C₁₆H₁₄Cl₂N₃S⁺·Br^-, the central thia-zolidine 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 <i>b-</i>axis direction. Weak C-H⋯π inter-actions, which only involve the minor disorder component of the ring, also contribute to the mol-ecular 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 inter-molecular inter-actions.
