title: 1-Phenyl-1-[(1-phenyl-ethyl)sulfonyl-methyl-sulfon-yl]ethane.
abstract: There are two mol-ecules in the asymmetric unit of the title compound, C(17)H(20)O(4)S(2). There are slight differences in the twist of the two rings relative to the S-C-S chain [dihedral angles of 48.41 (18) and 87.58 (16)° in the first mol-ecule and 45.98 (18) and 87.02 (18)° in the second] and the difference in the C-S-C-S torsion angles [176.68 (17) and -77.6 (2)° for the two independent mol-ecules].
