1,1′-Methyl­enebis{4-[(E)-2-(pyridin-4-yl)ethen­yl]pyridinium} dibromide dihydrate

ABSTRACT: Cations of the title compound inter­act via π–π inter­actions and hydrogen bond with water to form a zigzag ribbon. The chevron-shaped cations of the title hydrated salt, C25H22N42+·2Br−·2H2O, are arranged in back-to-back alternating directions to form a zigzag ribbon propagating along the [010] direction. Inter­molecular inter­actions comprising these ribbons are π–π inter­actions between the pyridinium and adjacent pyridyl rings, as well as O—H⋯O hydrogen bonding between water molecules and two adjacent pyridyl N atoms. Half of the cation is generated by the mirror plane. The water O atoms, the central C atom and one Br atom are located on this mirror plane while the other Br atom is on a twofold screw axis.
