In the title molecule, C16H10O8S2, the two aromatic rings form a dihedral angle of 87.97 (12)°. In the intermolecular O—H⋯O hydrogen bonds [O⋯O = 2.623 (3)–2.639 (3) Å] link the molecules into layers parallel to the ab plane.

2,2'-Disulfanediylditerephthalic acid (0.40 mg, 0.1 mmol), Mn(CH3COO)2 (0.28 mg, 0.11 mmol), NaOH (25 mg, 0.06 mmol) were added in methanol. The mixture was heated and stirred for six hours under reflux. The resultant was then filtered off to give a pure solution which was treated by diethyl ether in a closed vessel. One week later, single crystals were obtained.
All H atoms attached to C atoms or O atoms were fixed geometrically and treated as riding with C—H = 0.93 Å (aromatic) or O—H = 0.82 Å (hydroxyl group) with Uiso(H) = 1.2Ueq.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

The disulfide derivatives of the nicotinate - dithiodinicotinates - adopt usually a twisted structure with the C—S—S—C torsion of ca 90° in the solid state, that provides a possibility to show the axial chirality with M- and P-forms of the enantiomers (Li et al., 2008). Herewith we present the crystal structure of the title compound (Fig. 1), where torsion angle C—S—S—C is 91.80 (15)°.
In the crystal, intermolecular O—H···O hydrogen bonds (Table 1) link the molecules into layers parallel to ab plane.
