The title compound consists of C8H8S4 molecules where the tetrathiafulvalene backbone is nearly planar, and bond angles and distances are in accord with other TTF derivatives. The C—S—C angles for the five-membered rings of the TTF moiety average 95.83 (15)° for the ring containing the methyl groups and 94.37 (17)° for the unsubstituted ring. The molecules are stacked in pairs about an inversion center, with intermolecular SS distances of 3.932 (2) Å between adjacent molecules.
