4-(4-Amino­phenyl­sulfon­yl)aniline–1,3,5-trinitro­benzene (1/2)

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 mol­ecules of bis­(4-amino­phen­yl) sulfone (the drug Dapsone) and four mol­ecules of 1,3,5-trinitro­benzene 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 mol­ecules, the inter-ring dihedral anges are 69.6 (3) and 63.63 (9)°. Aromatic π–π inter­actions are also found between one of the Dapsone aromatic rings and a trinitro­benzene ring [minimum ring centroid separation = 3.596 (3) Å]. A 4-amino­phenyl ring moiety of one of the Dapsone mol­ecules and two nitro groups of a trinitro­benzene are disordered in a 50:50 ratio.
