3H-1,2-Benzodi-thiole-3-thione

摘要

The almost planar (r.m.s. deviation = 0.034??) title compound, C7H4S3, was synthesized by reacting 2,2-di-thiodi-benzoic acid with phospho-rus penta-sulfide in xylene solution. In the crystal, short S?S [3.3727?(14), 3.3765?(13) and 3.4284?(13)??] contacts and aromatic?π–π?stacking [shortest centroid–centroid separation = 3.618?(2)??] are observed.
