Die Kristallstruktur der unterfluorigen Säure: Kettenbildung durch OH…︁O‐Brücken

Abstract: Die Selbstassoziation von HOF im festen Zustand wurde durch Röntgenstrukturanalyse bei − 160°C untersucht; es liegen OH ⃛O‐Brücken vor. Als Protonacceptor der intermolekularen Wasserstoffbrückenbindung dient somit das Sauerstoffatom; OH ⃛F‐Brücken spielen keine Rolle.

“…The latter has been isolated in the form of several salts with O···O distances between 2.40 and 2.45 Å . A similar bridging situation as in 1 with tricoordinate oxygen is also present in crystalline hypofluoric acid, which contains polymeric -H·[··OF-H···]- chains with O···O distances of 2.89 Å …”

“…47 A similar bridging situation as in 1 with tricoordinate oxygen is also present in crystalline hypofluoric acid, which contains polymeric -H‚[‚‚OF-H‚‚‚]-chains with O‚‚‚O distances of 2.89 Å. 48 The O‚‚‚O distances between the hydrogen-bridged oxygen atoms in 1a-c ranging from 2.40 to 2.45 Å represent very strong hydrogen bonds. They are at the short end of the range of such bonds in H 3 O 2 -bridged metal complexes, 42 and they compare well with the free H 3 O 2 -ion 41 or the salts of the H 5 O 2 + ion.…”

“…This interpretation of the charge distribution is supported by calculations. 6 The final analysis of the solid-state structure of HOF 7 supports the formation of the hydrogen bond with oxygen as the electron donor.…”
