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—H...O interactions, together with close O...S contacts in the range 3.308 (3)–3.315 (3) Å, stabilize the packing.
