# Thiepane

Thiepane is the organosulfur compound with the formula $(CH_2)_6S.$ Thiepanes are seven-membered ring heterocycles that contains sulfide. The parent thiepane has seldom been studied.

A variety of derivatives are known. Hexathiathiepane (CAS RN 17233-71-5, m.p. 90 °C) is $CH_2S_6.$ A naturally occurring derivative is lenthionine, $1,4-(CH_2)_2S_5.$

Thiepane (hexathiophane) itself may be a product of spontaneous coal fires in post-mining waste heaps.
