The two title compounds, C22H28S and C23H30OS, respectively, have almost identical molecular structures, but different crystal structures. The two parts of each molecule are approximately perpendicular to each other, with S ...gamma H distances of 3.06 and 3.02 Angstrom, respectively, suitable for H-atom abstraction in photochemical reactions.
