The asymmetric unit of the title hydrated mol­ecular salt, C6H16N22+·2ClO4-·2H2O, contains a half dication (completed by inversion symmetry), a perchlorate anion and a water mol­ecule. The extended structure consists of infinite chains of formula [(ClO4)H2O]nn- ions extending along the b axis linked by Ow-H...O (w = water) hydrogen bonds. These chains are cross-linked by the dications via N-H...Ow and weak C-H...O hydrogen bonds, thus forming a three-dimensional supra­molecular network. Three-dimensional Hirshfeld surface analysis and two-dimensional fingerprint maps reveal that the structure is dominated by H...O/O...H and H...H contacts
