In the title compound, C 14 H 8 Cl 5 O 3 PS, the six-membered dioxaphosphorine ring exhibits a boat conformation with the S atom in an equatorial and the trichloromethyl group in an axial position. The benzene rings are oriented at dihedral angles of 17.77 (15) and 19.47 (19) with respect to the mea
