چکیده
In the title p-toluene-sulfonate salt of the drug dapsone, C12H13N2O2S(+)·C7H7O3S(-), the dihedral angle between the two aromatic rings of the dapsone monocation is 70.19 (17)° and those between these rings and that of the p-toluene-sulfonate anion are 72.34 (17) and 46.43 (17)°. All amine and aminium H atoms are involved in inter-molecular N-H⋯O hydrogen-bonding associations with sulfonyl O-atom acceptors as well as one of the sulfone O atoms, giving a three-dimensional structure.
