Another goal of this study was consideration of influence of fluorine on the hydrogen-bond pattern. Usually, especially in presence of oxygen atoms as potential acceptors, fluorine avoids involvement in hydrogen bonds in organic compounds (Dunitz & Taylor,

The B—F distances within the anion show considerable spread. Such a distribution of the B—F distances in the tetrafluoroborate anions is, however, usual as it was checked in the structures stored in the Cambridge Structural database (CSD; Version 5.32,
