The title compound, [Sn2(C6H5)6(C7H4O4S)], contains two molecules with similar conformations in the asymmetric unit. In each molecule, the Sn atoms adopt a distorted tetrahedral geometry arising from three C atoms of three phenyl rings and one O atom from the bridging 3-thienylmalonato ligand. The molecules lie about inversion centers with the ligands facing each other, with CO distances of 3.417 (10) and 3.475 (10) Å.
