2,2′-(Carbono­thio­yldisulfanedi­yl)bis­(2-methyl­propanoic acid)

The mol­ecular structure of the title compound, C₉H₁₄O₄S₃, exhibits intra­molecular C—H...S hydrogen bonds. In the crystal, pairs of O—H...O hydrogen bonds lead to the formation of centrosymmetric dimers, which are in turn connected by weak C—H...O inter­actions. The combination of these inter­actions generates edge-fused R₂²(8) and R₂²(20) rings running along [211].
