“…380, 386, 387 The most stable complex displays a geometry wherein the oxygen lone pairs are directed into the π face, and surprisingly good agreement among computational protocols has been found (Δ E lies between −1.6 and −2.1 kcal mol −1 , C 6 F 6 centroid⋅⋅⋅OH 2 : 3.2 Å in all cases) 386. The interaction values reported are only slightly higher than the orientationally averaged binding energy for water–hexafluorobenzene calculated from gas‐phase calorimetric data (−1.3 kcal mol −1 ) 387. Finally, as with other donors (for example, molecular oxygen),388, 389 the interactions are generally stronger with C 6 F 6 than with the parent C 6 H 6 .…”

“…Neutral molecules (of various polarity) possessing donor atoms also form complexes with perfluoroaromatic compounds; the interaction with water is the most well‐studied 379. 380, 386, 387 The most stable complex displays a geometry wherein the oxygen lone pairs are directed into the π face, and surprisingly good agreement among computational protocols has been found (Δ E lies between −1.6 and −2.1 kcal mol −1 , C 6 F 6 centroid⋅⋅⋅OH 2 : 3.2 Å in all cases) 386.

“…Neutralmoleküle (unterschiedlicher Polarität), die Donoratome enthalten, können ebenfalls Komplexe mit Perfluorarenen bilden; am häufigsten wurde hierbei die Wechselwirkung mit Wasser untersucht 379. 380, 386, 387 In der bevorzugten Struktur des C 6 F 6 ⋅OH 2 ‐Komplexes zeigen die freien Elektronenpaare des Sauerstoffatoms auf die π‐Fläche. Mit unterschiedlichen theoretischen Ansätzen wurden bei erstaunlich gut übereinstimmenden Werten die Komplexstabilitäten berechnet (Δ E im Bereich −1.6 bis −2.1 kcal mol −1 ; C 6 F 6 ‐Zentroid⋅⋅⋅OH 2 3.2 Å in allen Fällen) 386.…”

“…Mit unterschiedlichen theoretischen Ansätzen wurden bei erstaunlich gut übereinstimmenden Werten die Komplexstabilitäten berechnet (Δ E im Bereich −1.6 bis −2.1 kcal mol −1 ; C 6 F 6 ‐Zentroid⋅⋅⋅OH 2 3.2 Å in allen Fällen) 386. Der so erhaltene Δ E ‐Wert liegt nur geringfügig höher als die richtungsgemittelte Bindungsenergie des Wasser‐Hexafluorbenzol‐Komplexes, die anhand kalorimetrischer Daten aus der Gasphase (−1.3 kcal mol −1 ) berechnet wurde 387. Schließlich ist die Wechselwirkung von Wasser und anderen Donormolekülen (z.…”

“…The most studied lp··· complex is undoubtedly the hexafluorobenzene-water (C 6 F 6 -H 2 O) complex, which has been described in much detail both theoretically [7,8] and experimentally [9][10][11][12][13]. The interest in C 6 F 6 can be attributed to its use as a solvent in several spectroscopic techniques as well as its use as a standard in 19 F NMR and 13 C NMR.…”
