In the centrosymmetric tetranuclear title molecule, [Sn₄(C₆H₅)₈Cl₂O₂(OH)₂]·2C₂H₆OS, the two independent tin^IV atoms show distorted trigonal-bipyramidal SnC₂O₃ and SnC₂O₂Cl coordination geometries. The four tin^IV atoms are bridged by the hydroxo and oxo ligands, forming a ladder-like array of three edge-connected Sn₂O₂ squares. The solvent molecules are linked to the tetranuclear molecule via O-HO hydrogen bonds.
