2,2'-[p-Phenyl-enebis(methyl-idene-aza-ne-di-yl)]dipyridinium bis-(hydrogensulfate) dihydrate.

ABSTRACT: The cation of the title salt, C(18)H(20)N(4) (2+)·2HSO(4) (-)·2H(2)O, lies on a center of inversion with the mid-point directly in the middle of the p-phenyl-ene ring. Within the hydrogensulfate ion, the S-O(H) bond is the longest of the S-O bonds. The dihedral angle between the central and terminal ring of the cation is 78.6 (2)°. In the crystal, the cation, anion and water mol-ecule inter-act by O-H⋯O and N-H⋯O hydrogen bonds, generating a three-dimensional network.
