2-(Pyrene-1-yl)-1,3-dithiane

Abstract

In the title compound, C20H16S2, the pyrene ring is planar [maximum deviation 0.0144 (15) Å] and the dithiane ring adopts a chair conformation. The crystal packing is stabilized by C—H⋯π inter­actions. An intra­molecular C—H⋯S hydrogen bond generates an S(5) ring motif.

“…From the dithiane ring the benzene ring is in the expected equatorial position. These features are all common to dithiane crystal structures (Fun et al, 2009). Viewed down the c axis, the dithiane rings inter-leave ( Figure 2).…”
