2O:O')(thiophene-3-acetato-O)tetratin(IV)Abstract: In the centrosymmetric title compound, [Sn4(CH3)8(C6H5O2S)4O2], the central four-membered planar ring (Sn2O2) makes dihedral angles of 66.28 (12) and 77.43 (11)° with the heterocyclic rings of the bridging and monodentate ligands, respectively. One SnIV atom adopts a distorted SnO3C2 trigonal-bipyramidal geometry, with both C atoms in equatorial sites and the other a grossly distorted SnO4C2 octahedral or irregular arrangement. In the crystal, the molecules are connected into pillar-like polymeric units making R22(12) ring motifs due to intermolecular C-H
O interactions. C-H![[pi]](/logos/entities/pi_rmgif.gif)
interactions are also present. The O atoms of the chelating ligands and the S atom of the monodentate ligand are disordered over two sets of sites in a 0.65 (6):0.35 (6) ratio
