2-[(E)-2-(4-Ethoxy-phen-yl)ethen-yl]-1-methyl-pyridinium 4-bromo-benzene-sulfonate monohydrate.

ABSTRACT: In the title compound, C(16)H(18)NO(+)·C(6)H(4)BrO(3)S(-)·H(2)O, the cation exists in an E configuration with respect to the ethenyl bond and is slightly twisted with a dihedral angle of 8.5 (2)° between pyridinium and benzene rings. In the crystal, the cations are arranged in layers parallel to (100), with π-π inter-actions between pyridinium and benzene rings [centroid-centroid distances = 3.651 (3) and 3.613 (3) Å]. The anions and water mol-ecules are located between the cationic layers. The ions and water mol-ecules are linked into a three-dimensional framework by O-H⋯O and C-H⋯O hydrogen bonds.
