【 摘 要 】

The asymmetric unit of the title compound, C18H23N2O+·NO3−·0.5H2O, contains two independent 4-{4-[eth­yl(2-hy­droxy­eth­yl)amino]­styr­yl}-1-methyl­pyridin-1-ium cations, two nitrate anions and one lattice water mol­ecule. In the cations, the pyridine ring is twisted with respect by 7.98 (12) and 18.42 (10)° to the benzene ring. In the crystal, the cations, the anions and the lattice water mol­ecules are linked by O—H⋯O hydrogen bonds and weak C—H⋯O hydrogen bonds, forming a three-dimensional supra­molecular architecture. π–π stacking occurs between pyridine and benzene rings of adjacent cations, the centroid–centroid distances being 3.8169 (15) and 3.8663 (14) Å. In the crystal, one of the independent cations is disordered, the central vinyl unit and the terminal hy­droxy­lethyl group being disordered over two sets of sites with site occupancy factors of 0.600 (6) and 0.400 (6).
