Synopsis: Similar Hirshfeld surface shapes of the 1,1'-(ethane-1,2-diyl)dipyridinium dication are observed in its perchlorate and peroxo­di­sulfate salts. The asymmetric two-dimensional fingerprint plots and the preponderance of H...O inter­actions in the crystal structures are discussed.

Formula: C12H14N22+·2ClO4- and C12H14N22+·S2O82-
