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 Car—O [1.393 (9) and 1.397 (9) ] and ester S—O bond lengths [1.600 (5) and 1.590 (5) ] 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)°.
