5-(2-pyridyl)-1,3-dithiane-2-thione

The title compound, C9H9NS3, crystallizes with two molecules in the asymmet ric unit. In both molecules, the dithiane-2-thione rings adopt a symmetric half-boat conformation with the C atom opposite the C-S-thione bond out of the plane. The pyridine ring is in an equatorial position and is twisted ou t of the plane of the half-boat by 82.7 (2) and 84.5 (2)degrees in the two molecules, so that the N atom is trans to the axial C-H bond in both cases.
