3,4',5-Trichloro­biphenyl-4-yl 2,2,2-trichloro­ethyl sulfate

Crystals of the title compound, C₁₄H₈Cl₆O₄S, are twinned by inversion, with unequal components [0.85 (3):0.15 (3)]. The asymmetric unit contains two independent mol­ecules that are related by a pseudo-inversion center. The C_ar-O [1.393 (9) and 1.397 (9) Å] and ester S-O bond lengths [1.600 (5) and 1.590 (5) Å] of both mol­ecules are comparable to the structurally related 2,3,5,5-trichloro­biphenyl-4-yl 2,2,2-trichloro­ethyl sulfate. The dihedral angles between the benzene rings in the two mol­ecules are 37.8 (2) and 35.0 (2)°.
