Rosenbergite‐like fragments with geometries optimized in water, simulated by a PCM, were used to model Al hydroxyfluoride species in solution. The 19 F NMR shifts for the bridging F atoms in several such model complexes are very similar to those usually attributed to monomeric species such as Al(OH 2 ) 5 F 2+ in solution, suggesting that the ...
