Abstract: The asymmetric unit of the title compound, C₅H₈O₆S₂, consists of two spiro[5.5]undecane molecules. The nonplanar six-membered rings adopt chair conformations. In the crystal structure, weak intermolecular C-HO interactions, together with close OS contacts in the range 3.308 (3)-3.315 (3) Å, stabilize the packing.
