1-Hydroxy-4-methylpyridinium chloride

Abstract

The title salt, C6H8NO+·Cl−, contains two cations and two anions in the asymmetric unit. The components are linked by O—H...Cl and C—H...Cl hydrogen bonds, leading to tetra- (square-planar) or penta-coordinated (square-pyramidal) chloride ions. The title salt is isostructural with its bromide analogue.
