The cation is twisted, with dihedral angles between the pyridinium and benzene rings of 11.25?(13) and 10.7?(8)° for the major and minor components, respectively. In the crystal, the three components are linked into a centrosymmetric 2:2:2 unit by O-H?I and C-H?O hydrogen bonds. ?-? inter-actions with centroid-centroid distances of 3.5065?(7)-3.790?(9)?Å are also present.
