Abstract

The chevron-shaped cations of the title hydrated salt, C25H22N4 2+·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 - HO 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.
