3,4-Dimethyltetrathiafulvalene

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 S...S distances of 3.932 (2) Å between adjacent molecules.
