In the title molecular salt, 2C6H14N+·C14H8O4S22−, the complete dianion is generated by crystallographic twofold symmetry and a twisted conformation is found [the C—S—S—C torsion angle is 87.13 (2)° and the dihedral angle between the rings is 83.4 (2)°]. In the crystal, intermolecular N—H⋯O hydrogen bonds link the cations and anions.

The reaction was carried out under nitrogen atmosphere. 2,2'–Dithiodibenzoic acid (0.5 mmol) was dissolved in 10 ml methanol, and a solution of cyclohexylamine (1.0 mmol) in 20 ml toluene was added dropwise under intense agitation. The mixture was placed in air at room temperature. Suitable for X-ray analysis were obtained by slow evaporation of acetone solution over a period of two weeks. Analysis, calculated for [(C14H8O4S2)2-.2(C6H14N)+ (Mr = 504.69): C 61.87, N 5.55, H 7.19%; found: C 61.82, N 5.50, H 7.15%.
The H atoms were positioned geometrically with aromatic C—H distances of 0.93 Å, and refined as riding on their parent atoms, with Uiso(H) = 1.2 Ueq(C). The H atoms were positioned geometrically with cyclohexylamine C—H distances of 0.97 Å and refined as riding on their parent atoms, with Uiso(H) = 1.5 Ueq(C). The N—H distance is 0.89 Å with Uiso(H) = 1.2 Ueq(N).

The design and synthesis of novel coordination architectures has resulted in a great number of research efforts, due not only to their intriguing structural topologies, but also to their unexpected properties as functional materials (Sato et al., 1996; Yaghi et al., 1998). The main strategy popularly used in this area is the building–block approach. 2,2'–Dithiodibenzoic acid is a good choice in the design of novel coordination architectures, since its four coordination sites are likely to engage in coordination to metal ions. We report here the crystal structure, of new salt of 2,2-dithiodisalicylate with cyclohexylammonium cation. The title compound, (I) is composed of 2,2-dithiodisalicylate and cyclohexylammonium ions, in a ratio of 1:2; the asymmetric unit consists of one-half molecule of the 2,2-dithiodisalicylate and one cyclohexylammonium cation. A twofold axis of symmetry passes through the centre of the S—S bond. A twisted conformation is found for the anion [the C—S—S—C torsion angle is 87.13 (2)° and the dihedral angle between the rings is 83.4 (2)°]. There are two N—H···O intermolecular and one intramolecular hydrogen bonds, (Fig. 2 and Table 2).
