3',4'-Dichloro-biphenyl-4-yl 2,2,2-trichloro-ethyl sulfate
Abstract:
The four independent mol-ecules in the asymmetric unit of the title compound, C(14)H(9)Cl(5)O(4)S, are related by pseudo-inversion centres. The mol-ecules have C(aromatic)-O bond lengths ranging from 1.426 (10) to 1.449 (9) Å and biphenyl-4-yl sulfate ester bond lengths ranging from 1.563 (6) to 1.586 (6) Å, which is comparable to structurally related sulfuric acid diesters. The dihedral angles between the benzene rings range from 22.5 (4) to 29.1 (4)° and are significantly smaller than the calculated dihedral angle of 41.2°.
