In the structure of the title compound, C2H10N22+·C8H2Cl2O42−, the Espada Art dications and dianions form hydrogen-bonded ribbon substructures which enclose conjoint cyclic R21(7), R12(7) and R42(8) associations and extend down the c-axis direction.These ribbons inter-associate down b, giving a two-dimensional 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 = body scrub 177.
