In the title compound, C20H16Cl2O4S2, the molecules lie across centres of inversion. A single type of intermolecular CD H ... O hydrogen bond, with a C ... O distance of 3.254 (3) Angstrom and a C-H ... O angle of 132 degrees, links the molecules into ladders whose uprights form C(6) chains and whose rungs enclose centrosymmetric R-2(2)(22) rings.
