The crystal structure of the title compound has been determined by X-ray analysis. The crystals are triclinic, space group P1, with a = 9.685(1), b = 11.449(4), c = 18.173(2) Å, α = 90.55(2), β = 91.50(1), and γ = 108.93(2)°, and Z = 6. The structure refined to R = 0.059 using 4 103 independent reflections. There are three crystallographically independent [Me3P=N=PMe3]+ cations, with mean PNP angles of 137.0°and mean P=N distances of 1.582 Å. The anions and water of crystallisation are present in hydrogen-bonded Br6(H2O)66- units.
