Abstract: In the title salt, C14H13Br3NOS2+·Br-, synthesized by bromination of mesoionic 2-[2-(piperidin-1-yl)-1,3-dithiol-2-ylium-4-yl]phenolate in glacial acetic acid, the dihedral angle between the 1,3-dithiolium ring and the phenolic substituent ring is 45.9 (3)° due to the steric influence of the ortho-Br group on the 1,3-dithiolium ring. The piperidine ring adopts a chair conformation. In the crystal, the cation and anion are linked by an O-H...Br hydrogen bond.
