Bis(3-aza-niumylprop-yl)aza-nium hexa-chlorido-bis-muthate(III) monohydrate.

The asymmetric unit of the title compound, (C6H20N3)[BiCl6]·H2O, consists of a triprotonated bis-(3-aza-niumylprop-yl)aza-nium cation, two halves of an octahedral [BiCl6](3-) anion, each of the Bi(III) atoms lying on an inversion centre, and a water mol-ecule. In the crystal, the anions and water mol-ecules are linked by O-H⋯Cl hydrogen bonds, forming chains running parallel to [0-11]. The anionic chains and the cations are further linked into a three-dimensional network by N-H⋯Cl and N-H⋯O hydrogen-bond inter-actions.
