In aqueous solutions of ammonium fluoride , ammo- nium and fluoride ions have C.N. 4 [ 9 ] . It should be stressed that the fluoride ion has a high hydration energy [ 10 ] and that , therefore , the F -- H2O bond is a strong hydrogen ...

A similar situa- tion was previously observed for the fluoride solutions of aluminum with CH3NHCH2CH2NH2 , where , at sig- nificantly smaller molar ratios ( L : Al < 2 ) , about a third of aluminum was bound in fluorine - free complexes ...
