In the crystal structure of the title compound, C20H38N22+·2Br−, the centroid of the aromatic ring is located on an inversion center, so that the asymmetric unit consists of one-half molecule of the dication and one bromide anion. C—HBr interactions connect the two components into a three-dimensional network. An intramolecular C—Hπ interaction is also observed.

The asymmetric unit of the title compound, C20H28N2O6S2, contains one half-molecule, related to the other half by a twofold rotation axis. The two aromatic rings of the molecule make a dihedral angle of 50.91 (7)°. The O—CH2—CH2—O and N—CH2—CH2—O fragments both adopt gauche conformations, with torsion angles of 76.0 (4) and 70.4 (3)°, respectively. In the crystal, adjacent molecules are linked through N—HO hydrogen bonds into chains along the a-axis direction. The chains are further connected via C—HO interactions into a two-dimensional supramolecular network in the ac plane.
