title: 1,4-Bis(thio-phen-2-yl)butane-1,4-dione.
abstract: 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(thio-phene)-C bond. The non-H atoms of the mol-ecule 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 mol-ecules are linked via pairs of C-H⋯π contacts [H-centroid distances of the thio-phene units = 2.79 (9) and 2.82 (4) Å], in turn inter-digitating with each other along the bc plane, thus leading to an inter-woven two-dimensional network.
