The material adopts a more complicated structure in the liquid and solid states. If you do not respond, everything you entered on this page will be lost and you will have to login again. Olah went on to do extensive research on carbocations at Case Western and then the University of Southern California (Los Angeles). 1376-7. Find awards and scholarships advancing diversity in the chemical sciences. * Antimony Pentafluoride is a CORROSIVE CHEMICAL and contact can severely irritate and burn the skin and eyes with possible eye damage. Learn More. [4], Antimony pentafluoride is prepared by the reaction of antimony pentachloride with anhydrous hydrogen fluoride:[5], It can also be prepared from antimony trifluoride and fluorine. The crystalline material is a tetramer, meaning that it has the formula [SbF4(μ-F)]4.

The Sb-F bonds are 2.02 Å within the eight-membered Sb4F4 ring; the remaining fluoride ligands radiating from the four Sb centers are shorter at 1.82 Å. Learn how ACS can help you stay ahead in the world of chemistry. Safety. See our Browser Support/Compatibility page for supported browsers list. Find a chemistry community of interest and connect on a local and global level. Olah, G. A.; Prakash, G. K. S.; Wang, Q.; Li, X.-y. Antimony pentafluoride has also been used in the first discovered chemical reaction that produces fluorine gas from fluoride compounds: The driving force for this reaction is the high affinity of SbF5 for F−, which is the same property that recommends the use of SbF5 to generate superacids. The molecule can be notable for its current or historical importance or for any quirky reason. Promoting excellence in science education and outreach. The liquid contains polymers wherein each Sb is octahedral, the structure being described with the formula [SbF4(μ-F)2]n ((μ-F) denotes the fact that fluoride centres bridge two Sb centres). It can also be prepared by allowing fluorine to react … So where’s the magic? Its chief use is the fluorination of organic compounds. For your security, this online session is about to end due to inactivity. Edwards, A. J.; Taylor, P. "Crystal structure of Antimony Pentafluoride" Journal of the Chemical Society, Chemical Communications 1971, pp. Antimony pentafluoride reacts with most chemical compounds.

Breunig, Hans Uwe Wolf "Antimony and Antimony Compounds" in Ullmann's Encyclopedia of Industrial Chemistry 2006, Wiley-VCH, Weinheim. At Case Western, the researchers discovered that a mixture of HSO3F and SbF5easily dissolves paraffins. Structure and chemical reactions. It can protonate and dissolve almost all organic compounds and has several industrial uses, including catalysis and hydrofluorination. The second molecule, antimony pentafluoride (SbF5), was first reported in 1904. It can also be prepared from antimony trifluoride and fluorine.
