The title compound, C(13)H(20)O(3)S(5), is bis-ected by a crystallographic twofold rotation axis, which relates the two halves of the mol-ecule to one another: one S, one C and one O atom lie on the axis. The thione S atom lies in the plane of the five-membered rings with an r.m.s. deviation of 0.0042 (5) Å. Parts of the 17-membered macrocycle were refined using a two-part disorder model [occupancies of 0.553 (14) and 0.447 (14)]. There are no noteworthy inter-molecular inter-actions.
