In the title compound, C14H10O6S2, the dihedral angle between the planes of the two phenylene rings is 55.9 (1)°. Both hydroxy groups form intramolecular hydrogen bonds; however, one of them also engages in intermolecular hydrogen bonding. In the crystal, molecules are connected into helical chains by O—H⋯O hydrogen bonds. The crystal studied was an with a domain ratio of 0.51 (13):0.49 (13).

The title compound (I) was prepared as follows: To a solution of 5-(chlorosulfonyl)-2-hydroxybenzoic acid(19 mmol, 4.5 g) in conc. HCl (30 ml) cooled to 0 °C in an ice bath, Sn(118 mmol, 14.0 g) was added. The reaction mixture was stirred for 12 h and then refluxed for 6 h. The precipitate was separated and dissolved in Et2O. After filtration the organic layer was concentrated under reduced pressure to afford a solid that was subsequently purified by recrystallization using a mixture of EtOH and H2O. Yellow needle crystals of (I) were obtained by slow evaporation from EtOH/acetone/DMSO/DMF(5:1:3:3) after five months. Analysis calculated for C14H10O6S2: C 49.70, H 2.98%; found: C 49.18, H 2.75%.
All H atoms were placed in calculated positions and treated as riding, with C—H in the range 0.93–0.98 Å and with Uiso(H)=1.2–1.5Ueq(C).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
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. |

Hydrogen bonds and π–π stacking interactions play an important role in the self-assembly and recognition of aromatic compounds((Janiak, 2000; Hunter & Sanders, 1990) as an auxiliary stabilizing short contact (Orr et al., 1999; Kaafarani et al., 2001).
The two phenyl rings of the title compound are bonded with two S atoms at a distance of 1.781 (4)Å (S2—C13) and 1.793 (4) Å (S1—C6), and the C—C distances of two phenyl groups range from 1.371 (5) to 1.407 (6) Å (Figure. 1 and Table 1). Interestingly, there are intermolecular S···S interactions in the crystal structures, which are not common in diphenyl disulfide derivaties (Korp & Bernal, 1984; Kaitner & Pavlovic 1997; Ni et al., 2004; Sacerdoti et al., 1975). The intermolecular S···S interactions distance is 3.414 (2) Å, whereas the shorter intramolecular S—S distance is 2.051 (2) Å. The dihedral angle of these two phenyl rings is 55.9 (1)°, which is different from other molecules such as 4, 4'-dithiodiphenol (48.1 (2)°) (Ni et al., 2004) and diphenyl disulfide (76.7 (3)°) (Sacerdoti et al., 1975).
The crystal structure of 5, 5'-dithiodisalicylic acid demonstrates the self-assembly of molecules into three dimensional networks via hydrogen bonds(Table 2) and intermolecular S···S interactions.
