2-[(E)-2-(4-Ethoxy-phen-yl)ethen-yl]-1-methyl-quinolinium iodide dihydrate.

ABSTRACT: In the title compound, C(20)H(20)NO(+)·I(-)·2H(2)O, the cation is almost planar (r.m.s. deviation = 0.038 Å) and exists in an E configuration. The dihedral angle between the quinolinium ring system and the benzene ring is 0.7 (4)°. In the crystal structure, the cations are stacked in an anti-parallel manner along [100] with π-π inter-actions between the pyridinium and ethoxy-benzene rings [centroid-centroid distance = 3.678 (5) Å]. The cations, iodide anions and water mol-ecules are linked together through O-H⋯O, O-H⋯I and C-H⋯I hydrogen bonds into a two-dimensional network parallel to (001).
