Ionic Complexes Containing the Difluorochlorinium Cation

Abstract: The 1:l adducts between ClF, and the LEWIS acids BF,, PE;, AsF, and SbF, were ini-estigated. The existence of these complexes in the ionic form, in both the solid form and In solvents, such as JF5 and ClF,, was proven by I R , conductivity measurements, conductometric titration, and freezing point depression. It could be shown that the difluorochlorinium cation is bent and not linear.

“…The reaction mixtures were buffered to minimize changes in pH (6) For example, N. V. Sidgwick, "The Chemical Elements and Their Compounds," Oxford University Press, London, 1950, Vol. 1, p. 707, states, "NBrs is said to be a dark-red, explosive liquid (Millón, 1838) but it is very doubtful whether it has ever been prepared."…”

“…[9,10] With weaker Lewis acids, such as BF 3 and PF 5 , thermally unstable ClF 2 + salts, are formed. [11] This amphoteric character is common for all halogen trifluorides, XF 3 (X = Cl, Br, I). They can form bent, coordination around the Cl atom is extended by two highly ionic, long fluorine bridges to neighboring fluoridometallate anions, resulting in a total coordination number of six.…”

[ 11 ] This amphoteric character is common for all halogen trifluorides, X F 3 ( X = Cl, Br, I). They can form bent, C 2 v ‐symmetric X F 2 + cations and square planar D 4 h ‐symmetric [ X F 4 ] – anions, see Equation (1) and Equation (2) and Scheme 1.…”

“…Sulfuric and hydrobromic acids produce similar changes of less magnitude, the positions varying with acid concentration as reported by Fung. 10 The deshielding of amino proton peaks in such complex ions by anions has been recently interpreted by Millen and Watts11. to indicate ion association, possibly through proton bridges which lock the amino protons into axial and equatorial positions.…”
