2-[(E)-2-(4-Eth-oxy-phen-yl)ethen-yl]-1-methyl-pyridinium 4-chloro-benzene-sulfonate monohydrate.

ABSTRACT: In the title compound, C(16)H(18)NO(+)·C(6)H(4)ClO(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 9.85?(5)° between the pyridinium and the benzene rings. The anion is inclined to the cation with the dihedral angles between the benzene ring of the anion and the pyridinium and benzene rings of the cation of 78.33?(6) and 68.73?(6)°, respectively. In the crystal, the cations and anions are arranged alternately into head-to-head ribbons along the c axis, with the cationic ribbons stacked along the b axis. The crystal is consolidated by O-H?O hydrogen bonds, weak C-H?O and C-H?? inter-actions. ?-? inter-actions with centroid-centroid distances of 3.6111?(7) and 3.6466?(7)?Å are also observed.

The cation is disordered in such a way that the ethenyl units of the major and minor components are related by 180° around the long mol-ecular axis. In the major component, the cation is almost planar, the dihedral angle between the pyridinium and benzene rings being 0.8?(3)°, whereas in the minor component, the dihedral angle between the two aromatic rings is 4.2?(6)°. In the crystal, the cations are stacked in an anti-parallel manner along the a axis, while the anions and methanol mol-ecules are linked through O-H?O hydrogen bonds and Br?O short contacts [3.0248?(13)?Å] into a tape along the same direction. The three components are further linked by weak C-H?O, C-H?Br and C-H?? inter-actions.
