In the crystal of the title compound, C8H8N42+·2I3-·2C8H6N4·2H2O, inversion centres are located at the centroids of the central C-C bonds of the cation and the bpym molecules, as well as at the central I atoms of both anions. Intermolecular O-HN and N-HO hydrogen bonds are observed in the crystal structure.
