The title compound, octa-n-butyl-1κ2C,2κ2C,3κ2C,4κ2C-di-μ3-oxo-1:2:3κ3O;2:3:4:κ3O-tetrakis(thiophene-2-carboxylate)-1κO;1:2κ2O:O′;3:4κ2O:O′;4κO-tetratin(VI), [Sn4O2(C4H9)8(C5H3O2S)4], contains a planar Sn2O2 ring. The crystal structure is a racemic twin and shows pseudo-centrosymmetry. A previous structure determination of the title compound [Vatsa et al. (1990). J. Organomet. Chem. 396, 9–18] showed the same cell parameters but a centrosymmetric molecule in space group P21/c.
