Disulfur decafluoride

Disulfur Decafluoride, or S₂F₁₀, is a gas discovered in 1934 by Denbigh and Whytlaw-Gray. Each S of the S₂F₁₀ molecule is octahedral, and surrounded by 5 fluorines. S₂F₁₀ is highly toxic, with toxicity similar to phosgene. It was considered a potential chemical warfare agent in World War II because it does not produce lacrimation or skin irritation, thus providing little warning of exposure. It is a possible by-product of electrically decomposed SF₆, a gaseous insulator used in high voltage systems such as transmission lines, substations and switchgear.
