SUMMARY

Molecules of the title compound, C56H76Cl4O16S4, have crystallographic C2 symmetry and adopt a 1,3-alternate conformation where the four -OCH2CH2OCH2CH2Cl groups are located alternately above and below the virtual plane (R) defined by the four bridging S atoms. The dihedral angles between the plane . . .
