Chalkogenfluoride in niedrigen Oxydationsstufen. IX. Darstellung und Charakterisierung von SF3SSF

Lower Chalcogen Fluorides. IX. Preparation and Characterization of SF₃SSF During cocondensation of SF₂ and SSF₂ the new compound 1,3-Difluorotrisulphane-1,1-difluoride is formed in low yield and can be isolated by means of low temperature fractionation. The compound was unequivocally characterized by ¹⁹F-n.m.r,i.r.,Raman, and mass spectra. The unstable compound ist a colourless, viscous liquid with an extrapolated boiling point of 94°C and a melting point of ?62°C. It decomposes to SF₄ and SSF₂ in the gas phase.
