caption_attribution_description: chemical structure of zotepine
context_page_description: In organic chemistry, thiepine is an unsaturated seven-membered heterocyclic compound, with six carbon atoms and one sulfur atom. The parent compound, C₆H₆S is unstable and is predicted to be antiaromatic. Bulky derivatives have been isolated and shown by X-ray crystallography to have nonplanar C₆S ring.
  Theoretical studies suggest that thiepine would eliminate a sulfur atom to form benzene. The intermediate is this process is the bicycle thianorcaradiene. In the complex with Fe(CO)₃, the ring is stable.
  Benzothiepines have one fused benzene group and dibenzothiepines such as dosulepin and zotepine have two fused benzene groups. Damotepine is another thiepin derivative.
