This allotrope was first prepared by M. R. Engel in 1891 by treating thiosulfate with HCl. Cyclo-S6 is orange-red and forms a rhombohedral crystal. It is called ρ-sulfur, ε-sulfur, Engel's sulfur and Aten's sulfur. Another method of preparation involves the reaction of a polysulfane with sulfur monochloride: H2S4 + S2Cl2 → cyclo-S6 + 2 HCl (dilute solution in diethyl ether)
