Özet

The asymmetric unit of the title compound, C54H64O12S4, consists of one half of the molecule, which is located on an inversion centre. The heterocyclic six-membered ring adopts a distorted envelope conformation with the spiro C atom as the flap. In the crystal, molecules are linked by weak C-H center dot center dot center dot O hydrogen bonds with an R-2(2)(14) motif, forming a chain along the b-axis direction.
