4-Hy-droxy-1,2,6-tri-methyl-pyridinium bromide monohydrate.

ABSTRACT: The title salt, C8H12NO(+)·Br(-)·H2O, is isomorphous with the chloride analogue [Seethalakshmi et al. (2013). Acta Cryst. E69, o835-o836]. In the solid state, the cations, anions and water mol-ecules are inter-linked by a network of O-H?O, O-H?Br and C-H?Br inter-actions. The water mol-ecule makes two O-H?Br hydrogen bonds, generating [010] zigzag chains of alternating water mol-ecules and bromide anions. The cation is involved in two inter-molecular C-H?Cl inter-actions in the chloride salt, whereas three inter-molecular C-H?Br inter-actions are observed in the title bromide salt. This additional inter-molecular C-H?Br inter-action links the adjacent water and bromide zigzag chains via cationic mol-ecules. In addition, weak ?-? stacking inter-actions are observed between pyridinium rings [centroid-centroid distance = 3.5664?(13)?Å].
