چکیده
The title compound, C(7)H(4)N(2)O(6)·C(12)H(12)N(2)O(2)S, is a 1:1 cocrystal of the drug dapsone with 3,5-dinitro-benzoic acid. The dihedral angle between the two aromatic rings of the dapsone mol-ecule is 75.4 (2)°, and the dihedral angles between these rings and that of the 3,5-dinitro-benzoic acid are 64.5 (2) and 68.4 (2)°. A strong inter-molecular carb-oxy-lic acid O-H⋯N(amine) hydrogen bond is found, together with inter-molecular amine N-H⋯O hydrogen-bonding associations with carboxyl, nitro and sulfone O-atom acceptors. In addition, weak π-π inter-actions between one of the dapsone benzene rings and the 3,5-dinitro-benzoic acid ring [ring centroid separation = 3.774 (2) Å] results in a two-dimensional network structure.

The asymmetric unit of the title co-crystal, C(7)H(6)N(2)·C(7)H(4)N(2)O(6), contains two formula units of both components. The crystal structure is stabilized by inter-molecular O-H⋯O, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds, generating a two-dimensional wave-like network. π-π stacking inter-actions [centroid-centroid distances = 3.702 (2), 3.660 (2)and 3.671 (2) Å] stabilize the crystal packing.
