1,8-Bis(2-thienyl)-1,3,5,7-octatetrayne

Although the title compound, C₁₆H₆S₂, has parallel stacking of the molecules along the c axis, and the intermolecular distances between the C atoms of the triple bonds are within the required distance of 4.0 Å, these atoms are not positioned to form a 1,4-addition polymer. The thiophene rings are disordered over two different orientations, with 87:13 relative occupancies. The molecule has symmetry.
