In the title compound, the hydrated tetra(nitrate) salt of dapsone (4,4′-diaminodiphenylsulfone), 2C12H14N2O2S2+·4NO3−·H2O {alternative name: bis[bis(4,4′-diazaniumylphenyl) sulfone] tetranitrate monohydrate}, the cations are conformationally similar, with comparable dihedral angles between the two benzene rings in each of 70.03 (18) and 69.69 (19)°. In the crystal, mixed cation–anion–water molecule layers lying parallel to the (001) plane are formed through N—H...O, O—H...O and C—H...O hydrogen-bonding interactions and these layers are further extended into an overall three-dimensional supramolecular network structure. Inter-ring π–π interactions are also present [minimum ring centroid separation = 3.693 (3) Å].
