Antimony pentafluoride is the chemical compound with the formula sbf5. This colourless, viscous liquid is a valuable lewis acid and a component of the superacid fluoroantimonic acid, the strongest known acid. Some features that give the compound scientific interest are its lewis acidity and that it also reacts with almost all known compounds. 
Arsenic pentafluoride is a chemical compound of arsenic and fluorine. The oxidation state of arsenic is +5.
Bromine pentafluoride, BrF5, is an interhalogen compound and a fluoride of bromine. It is a strong fluorination reagent.
Chlorine pentafluoride has formula ClF5. It was first synthesized in 1963.
Iodine pentafluoride, IF5, is a fluoride of iodine. It is a colourless or yellow liquid with a density of 3250 kg m−3. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas.

Disulfur decafluoride (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 pulmonary agent in World War II because it does not produce lacrimation or skin irritation, thus providing little warning of exposure.
Trifluoromethyl Sulfur Pentafluoride
Trifluoromethyl sulfur pentafluoride (SF5CF3), which is a newly discovered compound in the troposphere and chemically similar to SF6, has been listed as a potent greenhouse gas because of its high global warming potential close to 20,000 and its long lifetime of about 800 years in the atmosphere. From the environmental and ecological points of view, it is urgent to understand the environmental fate of this unique material, including octanolwater partition coefficient (Kow), water solubility (S) and Henry's law constant (KH).
