Halogen Fluorides And Other Covalent Fluorides - Physical And Chemical Properties

Crystal and Molecular Structure of Difluorochlorine(III)-hexafluoroarsenate(V), ClF2AsF6

“…It is possible that for the bromine compound, structure 2 has more importance. It has been pointed out that the physical properties of BrF2SbF6 suggest extensive fluorine bridging (18). The infrared and Raman spectra of both BrF2AsF6 and BrF2SbF6 (19,20) are more complicated than their chlorine analogues (3-5); however, this could be due to the fact that the arsenic and antimony atoms in C1F2AsF6 and C1F2SbF6 lie on centers of symmetry reducing the number of bands by the operation of the mutual exclusion rule.…”

Chemical Analysis of the Alkali Metal Tungsten Bronzes.

“…Gutmann reports that the hexafluoride does not react with the solvent to produce an acidic solution (60). However, Clark states that the solution is weakly acid (29). It has been observed for potassium, rubidium, and cesium that the following reaction occurs (30, 33):…”

Recent Advances in Fluorine Chemistry and Technology

“…In 1949, it was discovered that BrF 3 and IF 5 , but not the other halogen fluorides, have a high electrical conductivity and form a series of compounds indicating that the liquid halogen fluorides are appreciably self-ionized as (45) 2BrF 8^B rF 2 + + BrF 4 -2IF 5 ^ IF 4 + + IF 6 -Thus when, for example, KF is dissolved in these materials and the excess halogen fluoride is evaporated, the new compounds KBrF 4 and KIF 6 remain. These compounds may be thought of as bases, in the same way that KOH is a base in water (133).…”
