Chemistry:Trifluorosulfate

From HandWiki

Trifluorosulfate is an ion with the formula SO2F3.[1] This term is ambiguous with three fluorosulfate ions (SO3F)3. It can also be confused with the trifluoromethyl sulfate ion.[2]

Properties

Chemical structure of the trifluorosulfate anion

The trifluorosulfate ion has a distorted trigonal bipyramid shape with C2v symmetry. On the equator are two oxygen atoms with a bond to sulfur of length 143.2 pm. Also one fluorine atom on the equator has a bond length of 157.9 pm. The two other fluorine atoms at the apexes of the pyramids have bond lengths 168.5 pm and form an angle ∠FSF of 165.2°.[1]
