چکیده
Mol-ecules of the title compound, [Sn(2)(C(6)H(5))(6)(C(6)H(2)O(4)S)], lie on inversion centres with the central thio-phene ring disordered equally over two orientations. The carboxyl-ate groups are approximately coplanar with the thio-phene ring [dihedral angle = 4.0 (1)°] and the Sn-O bond distance of 2.058 (4) Å is comparable to that in related organotin carboxyl-ates.

In the title compound, C14H16O4S2, the thieno[2,3-b]thio-phene ring systems are planar [maximum deviation = 0.008 (2) Å]. The mol-ecular conformation is stabilized by intra-molecular C-H⋯O hydrogen bonds, while the crystal packing is stabilized by C-H⋯O, C-H⋯π and π-π stacking [centroid-centroid distance = 3.6605 (14) Å] inter-actions, which lead to supra-molecular layers in the ab plane.
