The crystal structure of the title compound, C6H10N22+·2Cl−, has been reported previously in the non-standard setting P21/a [Genet (1965). Bull. Soc. Fr. Miner. Crist. 88, 463–470], with an R value of 0.16. The current redetermination improves significantly the precision of the geometric parameters. In the crystal packing, cations and anions are linked by intermolecular N—H...Cl and C—H...Cl hydrogen bonds into a three-dimensional network.
