Descripción
Sumario:The chevron-shaped cations of the title hydrated salt, C(25)H(22)N(4) (2+)·2Br(−)·2H(2)O, 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.
