1,4-Bis(thio­phen-2-yl)butane-1,4-dione

In the centrosymmetric title compound, C(12)H(10)O(2)S(2), the alkyl chains adopt a fully extended all-trans conformation with respect to the C(thio­phene)—C bond. The non-H atoms of the mol­ecule are nearly planar, with a maximum deviation of 0.063 (2) Å from the mean plane of the constituent atoms. In the crystal, symmetry-related mol­ecules are linked via pairs of C—H⋯π contacts [H–centroid distances of the thio­phene units = 2.79 (9) and 2.82 (4) Å], in turn inter­digitating with each other along the bc plane, thus leading to an inter­woven two-dimensional network.
