nformation about the central C-C bond. The molecule is centrosymmetric
and exhibits regular alternation of the phenylthio side-chain units a
bove and below the mean plane of the 14 C atoms of the diphenylethane
skeleton. In contrast, the ethylene link unit has. a syn relationship
with respect to the phenyl groups of the phenylthio substituents in th
