Bis(3-methylanilinium) naphthalene-1,5-disulfonate

Abstract

In the crystal of the title molecular salt, 2C7H10N+·C10H6O6S22−, the naphthalene-1,5-disulfonate anion is located on an inversion center and accepts N—H...O hydrogen bonds from the 3-methylanilinium cations, forming supramolecular layers parallel to the ac plane.
