description

In the title compound, 4CH6N+·C10H2O8 4−·2H2O, the complete C10H2O8 4− anion is generated by inversion; one of the unique carboxylate groups is almost coplanar with the benzene ring, perhaps as the result of intramolecular C—H...O interactions, and the other is almost perpendicular. A network of O—H...O and N—H...O hydrogen bonds helps to consolidate the crystal packing.
