The asymmetric unit of title hydrated salt, C22H46N42+·2Cl-·4H2O, comprises half a centrosymmetric dication, one Cl- anion and two water molecules of crystallization. The structure determination reveals that protonation has occurred at diagonally opposite amine N atoms, and that the dication features intramolecular N-HN hydrogen bonds. In the crystal, a three-dimensional artchitecture is formed by O-HCl/N and N-HCl/O hydrogen bonds.
