Abstract
In the molecular structure of the title compound, C20H42S2, (I), the skelet on of the hydrocarbon has an all-trans conformation. The terminal S-H bond is in a gauche conformation with respect to the skeleton. In the crystal st ructure, the molecules are arranged along the c axis, the longest axis, for ming layers in which the long axis of the molecule is inclined to the layer plane. This packing is very similar to that of the smectic C structure of liquid crystals. Except for the length of the c axis, no big difference was observed between the crystal data obtained here and those of homologues wi th even numbers of C atoms already reported.
