Abstract: The structure of the title compound, C7H4OS4, at 100 K has orthorhombic symmetry. In the crystal, tetrathiafulvalene molecules form -stacks along the a axis, with a stacking distance of 3.4736 (6) Å. Along the b axis, parallel stacks are interconnected with each other through a network of weak C-HO hydrogen bonds and short SS contacts [3.4813 (7) Å]. Additional short SS contacts [3.4980 (9) Å] join parallel stacks along the c axis.
