The asymmetric unit of the title compound, C16H34N42+ center dot- 2I(-) center dot 2H(2)O, contains one half-cation, one iodide anion and one water molecule. The cation has crystallographically imposed centrosymmetric symmetry. Despite some differences in the unit-cell dimensions, packing analysis on a cluster of 15 cations and a comparison of the hydrogen bonding suggests that this compound is isostructural with its bromide analogue. Intermolecular hydrogen bonding forms eight-membered [H-OH center dot center dot center dot I](2) and [H-N-H center dot center dot center dot I](2) rings and creates a sheet structure.
