Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Wissenschaftliche Zeitschrift – Karl-Marx-Universitaet Leipzig, Mathematisch-Naturwissenschaftliche Reihe called Determination of absolute binding energies in molecules and solids, Author is Leonhardt, G., which mentions a compound: 13940-83-5, SMILESS is [H]O[H].[H]O[H].[H]O[H].[H]O[H].[Ni+2].[F-].[F-], Molecular F2H8NiO4, Reference of Nickel(ii)fluoridetetrahydrate.
Ionization energies of gaseous substances determined on various apparatus with UV and x-ray excitation agree with one another by ≤0.1 eV. The values, obtained by ΔSCF-calculations, for the inner electrons correspond to several 0.1 eV from experiment The charging corrections on solid substances give for the various apparatus and different correction processes (hydrocarbon contamination and Au-decoration techniques) a deviation of EiF values of ≲0.3 eV. By determination of the spectral width (difference between high- and low-energy edges for the kinetic energy) binding energies Eiv can be determined from the exptl. values of EiF and EiVB-values at the vacuum level. The importance of such data for the study of the electronic mutural exchange (polarization, electrom affinity) and the position of the Fermi level in solids is discussed.
After consulting a lot of data, we found that this compound(13940-83-5)Reference of Nickel(ii)fluoridetetrahydrate can be used in many types of reactions. And in most cases, this compound has more advantages.
