Abstract: The asymmetric unit of the title compound, C₁₆H₂₁O₅PS, contains two symmetry-independent molecules. The overall molecular geometry of both molecules is very similar. The coumarin ring systems are only insignificantly distorted from planarity. In the structure, C-HO and C-H weak intermolecular hydrogen bonds can be found. In addition, stacking interactions between the rings are present.
