“…In 1999 a crystal structure of the diprotonated oxalic acid co-crystalized with four molecules of water was already reported. [6] This crystal structure raises general questions, since it is unlikely that in a superacidic medium the molecule of lower basicity (oxalic acid) is protonated before the more basic water. Consequently, we examined the behavior of oxalic acid in superacidic media.…”

“…According to crystal structure analysis, 202 the ion F 3 S þ is of C 3v symmetry and has very short SÀF bonds (1.495 and 1.499 A ) indicative of a substantial positive charge on sulfur. 206 The cations in Br 3 S þ SbF 6 À and Cl 3 S þ SbCl 6 À , in turn, were shown to have significantly shortened sulfur-halogen bonds and distorted octahedral arrangement around sulfur, when cation-anion secondary bonding interactions are taken into account. 200 Various Cl 3 S þ M n À salts were prepared by Kolditz and Sch€ afer 203 (M n ¼ AsF 6 , oxidative chlorination of sulfur with AsCl 3 -AsF 3 ), Minkwitz and Gerhard 204 [Eq.…”

“…Unter Verwendung von AsF 5 als Lewissa È ure kann kein stabiles Produkt isoliert werden. [22]. Die Sb±F-Absta È nde der an den kurzen O´´´F-Kontakten beteiligten Fluoratome sind gegenu È ber terminalen Sb±F-Gruppen geringfu È gig aufgeweitet.…”

“…Dies kann auf die sta È rkeren O´´´F-Kontakte im (CF 3 ) 2 C(F)OH 2 + Sb 2 F 11 ± zuru È ckgefu È hrt werden. Im protonierten Methanol CH 3 OH 2 + MF 6 ± werden die O±X-Valenzschwingungen in einem a È hnlichen Bereich von 3144 bis 3080 cm ±1 beobachtet [22]. Die beobachteten H/D-Shifts zwischen (CF 3 ) 2 C(F)OH 2 + und (CF 3 ) 2 C(F)OD 2 + entsprechen in guter Na È herung der Produktregel von Redlich und Teller [45].…”
