The crystal structure of -methylthio-1,2,3,4-tetrahydronaphthalene-1,8
-diyl dibenzoate contains two independent molecules. These molecules h
ave a similar conformation except for the dihedral angles between the
aromatic ring and the benzoyloxy group linked to it, which differ by a
relative rotation of -160-degrees. The absolute configurations of the
two chiral centres C8 and C10 are established as S and S.
