Structure and synthesis
Like other 1,4-dithiins but unlike its oxygen analog dibenzodioxin, the shape of thianthrene is not planar. It is bent, with a fold angle of 128° between the two benzo groups.
Thianthrene can be prepared by treating benzene with disulfur dichloride in the presence of aluminium chloride.
