The asymmetric unit of the title co-crystalline 1:2 adduct, C(12)H(12)N(2)O(2)·2C(6)H(3)N(3)O(6), contains two independent mol-ecules of bis-(4-amino-phen-yl) sulfone (the drug Dapsone) and four mol-ecules of 1,3,5-trinitro-benzene and is extended into a two-dimensional hydrogen-bonded network structure through amino N-H⋯O hydrogen-bonding associations with nitro O-atom acceptors. In the two independent Dapsone mol-ecules, the inter-ring dihedral anges are 69.6 (3) and 63.63 (9)°. Aromatic π-π i ...[more]
