(E)-2-[4-(Diethyl­amino)­styr­yl]-1-ethyl­pyridinium iodide monohydrate

In the title hydrated salt, C(19)H(25)N(2) (+)·I(−)·H(2)O, the 4-(diethyl­amino)­phenyl unit of the cation is disordered over two positions in a 0.847 (3):0.153 (3) ratio. The cation is twisted, with dihedral angles between the pyridinium and benzene rings of 11.25 (13) and 10.7 (8)° for the major a...

Sumario:In the title hydrated salt, C(19)H(25)N(2) (+)·I(−)·H(2)O, the 4-(diethyl­amino)­phenyl unit of the cation is disordered over two positions in a 0.847 (3):0.153 (3) ratio. 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. π–π inter­actions with centroid–centroid distances of 3.5065 (7)–3.790 (9) Å are also present.
