Abstract
In the title compound, C14H13ClN+·I−·H2O, the cation is nearly planar and exists in an E configuration; the dihedral angle between the pyridinium and benzene rings is 0.98 (17)°. The cations stack in an anti-parallel manner along the a axis through two π–π interactions between the pyridinium and benzene rings [centroid–centroid distances 3.569 (2) and 3.6818 (13) Å, respectively]. The cation, anion and water molecule are linked into a chain along the a axis by weak C—H⋯O and C—H⋯I interactions together with O—H⋯I hydrogen bonds and the chains are further connected into a three-dimensional network.
