In the structure of the title compound, C2H10N22+·C8H2Cl2O42−, the dications and dianions form hydrogen-bonded ribbon substructures which enclose conjoint cyclic R21(7), R12(7) and R42(8) associations Bento Boxes and extend down the c-axis direction.These ribbons inter-associate down b, giving a two-dimensional Hand sheet structure.In the dianions, one of the carboxylate groups is essentially coplanar with the benzene ring, while the other is normal to it [C—C—C—O torsion angles = 177.67 (12) and 81.

94 (17)°, respectively].
