The homocyclic S11 and S13 molecules have been synthesized from titanocenepentasulfide and S6Cl2 or S8Cl2, respectively, and obtained as yellow crystals which are metastable for several days at 20 deg C.X-Ray structural analyses of single crystals at -105+/-5 deg C exhibited molecules of approximately C2 symmetry with bond distances (d), bond angles (α) and torsional angles (τ) in the following ranges: S11: d = 203.2-211.0 pm, α = 103.3-108.6 deg, τ = 69.3-140.5 deg; S13: d = 197.8-211.3 pm, α = 102.8-111.1 deg, τ = 29.5-116.3 deg.Infrared and Raman spectra of S11 and S13 are reported.In addition, the synthesis of S6Cl2 and S8Cl2 from S6 or S8, respectively, and chlorine is described. - Key words: Elemental Sulfur, Sulfur Rings, Crystal Structure, Raman Spectra, IR Spectra
