Crystal structure and Hirshfeld surface analysis of 3-amino-5-phenyl­thia­zolidin-2-iminium bromide

In the cation of the title salt, C(9)H(12)N(3)S(+)·Br(−), the thia­zolidine ring adopts an envelope conformation with the C atom adjacent to the phenyl ring as the flap. In the crystal, N—H⋯Br hydrogen bonds link the components into a three-dimensional network. Weak π–π stacking inter­actions between the phenyl rings of adjacent cations also contribute to the mol­ecular packing. A Hirshfeld surface analysis was conducted to qu­antify the contributions of the different inter­molecular inter­actions and contacts.
