چکیده
In the crystal structure of the title compound, C(8)H(14)N(3) (+)·Br(-)·2H(2)O, inter-molecular O-H⋯O and O-H⋯Br hydrogen bonding occurs. The water mol-ecules are connected into chains extending in the a-axis direction. The bromide anions are connected to the water mol-ecules, forming 10-membered rings. The cations are connected to the anions via weak C-H⋯Br inter-actions. Two carbon atoms of the cation are disordered and were refined using a split model (occupancy ratio 0.70:0.3).

In the title compound, C(8)H(14)N(3) (+)·BF(4) (-)·H(2)O, the cation, anion and water molecule all lie on mirror planes. The BF(4) (-) anion is disordered over two orientations with occupancies refined to 0.57 (2) and 0.43 (2). The water mol-ecule is linked to the cation via an O-H⋯N hydrogen bond. Weak inter-molecular O-H⋯F, C-H⋯O and C-H⋯F hydrogen bonds consolidate the crystal packing.
