In the title p-toluene­sulfonate 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-toluene­sulfonate anion are 72.34 (17) and 46.43 (17)°. All amine and aminium H atoms are involved in inter­molecular 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.

Dapsone [4-(4-aminophenylsulfonyl)aniline] is a very weak Lewis base which finds use as an anti-leprotic, anti-malarial and leprostatic drug (Wilson et al., 1991). The structure of four dapsone solvates are known: the 0.33hydrate (Kus'mina et al., 1981) and the (2:1) dichloromethane, (1:1) 1,4-dioxane and (1:1) tetrahydrofuran solvates (Lemmer et al., 2012) but adducts or salts of this compound are not common. We have reported the structures of a (1:2) co-crystalline adduct with 1,3,5-trinitrobenzene (Smith & Wermuth, 2012a) and (1:1) adducts with 3,5-dinitrobenzoic acid (Smith & Wermuth, 2012b) and 5-nitroisophthalic acid (Smith & Wermuth, 2013) but only one proton-transfer salt structure is known, with 3,5-dinitrosalicylic acid (a monohydrate) (Smith & Wermuth, 2013). Reported herein is the structure of a second salt of dapsone, with p-toluenesulfonic acid, C12H13N2O2S+ C7H7O3S-.

In the structure of the title salt (Fig. 1), the conformation of the dapsone monocation as indicated by the inter-ring dihedral angle [70.19 (17)°], compares with 78.27 (9)° in the 3,5-dinitrosalicylic acid salt (Smith & Wermuth, 2013) and 75.4 (2)° in the 3,5-dinitobenzoic acid adduct (Smith & Wermuth, 2012b). The conformation of the title compound is influenced by short intramolecular ring CH···Osulfone interactions [C6—H···O12, 2.918 (4) Å and C21—H···O12, 2.925 (4) Å]. The angles between the p-toluenesulfonate ring and the aniline and anilinium rings respectively, are 46.43 (17) and 72.34 (17)°.

In the crystal, all amine and aminium H-atoms are involved in intermolecular N—H···O hydrogen-bonding associations with sulfonyl O-atom acceptors as well as with one of the sulfone O-atoms (O11) (Table 1). The resulting structure is a three-dimensional framework (Fig. 2). No ππ interactions are found between the cation and anion ring systems [minimum ring centroid separation = 4.534 (2) Å].

Experimental top

The title compound was prepared by the reaction of 4-(4-aminophenylsulfonyl)aniline (dapsone) with p-toluenesulfonic acid by heating together for 15 min under reflux, 1 mmol quantities of the two reagents in 50 ml of 50% ethanol–water. Partial room-temperature evaporation of the solvent provided poorly-formed colourless crystal aggregates of the title salt from which a specimen was cleaved for the X-ray analysis.

Refinement top

All H atoms potentially involved in hydrogen-bonding associations were located in a difference-Fourier analysis but were subsequently constrained, with Uiso(H) = 1.2Ueq(N). Other H-atoms were included at calculated positions [C—H = 0.95 Å (aromatic) or 0.98 Å (methyl)] and also treated as riding, with Uiso(H) = 1.2 or 1.5Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
