The title compound, C14H28O2S4, possesses a crystallographically imposed inversion centre and has two methine C atoms linked to methoxymethyl functional groups. It is in the exodentate conformation, with the four S atoms lying on the edges of the 'rectangular' macrocycle. The lone pairs of electrons on the S atoms point outwards from the macrocyclic cavity and the S atoms are bridged alternately by one-carbon and four-carbon moieties.
