Each S of the S<sub>2</sub>F<sub>10</sub> molecule is [[octahedral]], and surrounded by 5 fluorines. S<sub>2</sub>F<sub>10</sub> 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 [[Sulfur hexafluoride|SF<sub>6</sub>]], a gaseous [[Electrical insulation|insulator]] used in high voltage systems such as [[transmission lines]], [[Electrical substation|substation]]s and [[switchgear]]. ==External links== *[http://www.cdc.gov/Niosh/pel88/5714-22.html CDC page on the substance's toxicology] ==References== {{Citationstyle|date=September 2007}} <references/> * {{cite book | Editors = Christophorou, Loucas G., [[Isidor Sauers]] | year = 1991 | title = Gaseous Dielectrics VI | publisher = Plenum Press | id = ISBN 0-306-43894-1 }} [[Category:Chemical weapons]] [[Category:Sulfur fluorides]] {{inorganic-compound-stub}}
