Abstract

In the title mol-ecular salt, C₂₆H₂₄N₃S⁺·Br^-, the dihedral angles between the thia-zole ring and its attached phenyl and benzoyl rings are 54.81 (7) and 85.51 (7)°, respectively. In the crystal, ion pairs are linked by C-H⋯Br and N-H⋯Br hydrogen bonds and are connected into helical chains extending along the c-axis direction by weak, electrostatic S⋯Br^- inter-actions. A Hirshfeld surface analysis was performed, which showed the dominant role of H⋯H contacts (51.3%).

Keywords: crystal structure; dihydronaphthalene; hydrazinium salt; hydrogen bond; thiazole.
