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.
