2-(1,3-Dithiol-2-ylidene)-1,3-dithiole-4-carbaldehyde

Abstract

The structure of the title compound, C7H4OS4, at 100 K has orthorhombic symmetry. In the crystal, tetrathiafulvalene molecules form π-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 - H...O hydrogen bonds and short S...S contacts [3.4813 (7) Å]. Additional short S...S contacts [3.4980 (9) Å] join parallel stacks along the c axis.
