5-Bromo-4-(35-di­bromo-2-hy­droxy­phen­yl)-2-(piperidin-1-yl)-13-di­thiol-2-ylium bromide

摘要

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.
