(E)-1-Methyl-4-styrylpyridinium iodide monohydrate
Abstract:
In the title compound, C(14)H(14)N(+)·I(-)·H(2)O, the cation is essentially planar, with a dihedral angle of 2.55 (7)° between the pyridinium and phenyl rings, and exists in an E configuration with respect to the ethenyl bond. In the crystal structure, the cations are stacked in an anti-parallel manner along the a axis. The cation is linked to the water mol-ecule by a weak C-H⋯O inter-action, and the water mol-ecule is further linked to the I(-) ion by O-H⋯I hydrogen bonds. The crystal structure is consolidated by these inter-actions and is further stabilized by a π-π inter-action between the pyridinium and phenyl rings with a centroid-centroid distance of 3.6850 (8) Å.
