Hexasulfur
Chemical compound / From Wikipedia, the free encyclopedia
Hexasulfur is an inorganic chemical with the chemical formula S6. This allotrope was first prepared by M. R. Engel in 1891 by treating thiosulfate with HCl.[2] Cyclo-S6 is orange-red and forms a rhombohedral crystal.[3] It is called ρ-sulfur, ε-sulfur, Engel's sulfur and Aten's sulfur.[4] Another method of preparation involves the reaction of a polysulfane with sulfur monochloride:[3]
- H2S4 + S2Cl2 → cyclo-S6 + 2 HCl (dilute solution in diethyl ether)
