Potassium 2-[(2-carboxy­phen­yl)disulfan­yl]benzoate–2,2′-disulfanediyl­dibenzoic acid (1/1)

摘要

In the title compound, K⁺·C14H9O4S2 ⁻·C14H10O4S2, the hydrogen 2,2′-dithio­dibenzoate and 2,2′-disulfane­diyl­di­ben­zoic acid species combine to provide an O6S2 donor set to the potassium cation based on a cubic geometry. K⋯S [3.1733 (7) and 3.5499 (8) Å] and K⋯O [2.6586 (16)–3.0661 (15) Å)] inter­actions, coupled with O—H⋯O hydrogen bonding, lead to the formation of supra­molecular chains along [010].
