In the title compound, C6H7BrN+·PF6−·H2O, N—H⋯F, N—H⋯O and O—H⋯F hydrogen-bonding interactions stabilize the crystal structure and give rise to to chains running parallel to the c axis. In the anion, four of the F atoms are disordered over two sets of sites of equal occupancy.
The title compound was synthesized as part of our group’s search for ferroelectric compounds, which usually have a phase transition. For background to phase transition materials, see: Li et al. (2008 ▶); Zhang et al. (2009 ▶).
