Sulfur hexafluoride - Wikipedia

A main contribution to the inertness of SF 6 is the steric hindrance of the sulfur atom, whereas its heavier group 16 counterparts, such as SeF 6 are more reactive than SF 6 as a result of less steric hindrance (See hydrolysis example). It does not react with molten sodium below its boiling point, but reacts exothermically with lithium.
