Electric Literature of F2H8NiO4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Nickel(ii)fluoridetetrahydrate, is researched, Molecular F2H8NiO4, CAS is 13940-83-5, about Nuclear magnetic resonance study of some paramagnetic hydrated fluorides. Author is Easwaran, K. R. K.; Srinivasan, Ramaswami.
N.M.R. studies of proton and F nuclei are reported in a series of compounds MF2.4H2O, where M is Fe, Co, Ni, and Zn. The spectra of the 3 paramagnetic salts were different from those of the diamagnetic ZnF2.4H2O. Proton resonance studies of the paramagnetic members have shown marked changes in line width on cooling from room temperature to 90°K. The 19F resonance in the paramagnetic salts in polycrystalline from have shown large shifts which were temperature dependent. The results are discussed in terms of the hyperfine fields owing to the unpaired electrons of the paramagnetic ions.
From this literature《Nuclear magnetic resonance study of some paramagnetic hydrated fluorides》,we know some information about this compound(13940-83-5)Electric Literature of F2H8NiO4, but this is not all information, there are many literatures related to this compound(13940-83-5).
