Article title edit
I think a better title for this article is cyclooctasulfur (5320 Google hits). The current title octathiocane (1820 Google hits) is less common and uses organic nomenclature for an inorganic molecule.
Thiocane is Hantzsch–Widman nomenclature for cyclo-(CH2)7S, i.e. cyclooctane with one methylene (CH2) group replaced by a sulfur atom. You can see from the pattern below where the name octathiocane comes from, but it doesn't make much sense because S8 is not a heterocyclic molecule (it's a homocyclic molecule). Hantzsch–Widman nomenclature only applies to heterocycles.

OK, no objections here. Plasmic Physics (talk) 15:07, 26 July 2011 (UTC)
- I tried to do the move, but cyclooctasulfur already exists as a redirect. I'll ask an admin. I was interesting looking into all the possible thiocanes – might spawn a new article. --Ben (talk) 15:21, 26 July 2011 (UTC)
