title: 1-Cyano-methyl-4-aza-1-azonia-bicyclo-[2.2.2]octane bromide dihydrate.
abstract: 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).
