Description
Effects of partial substitution of Zn by Mn on the electronic and atomic structure of diphosphates Zn2–xMnxP2O7*5H2O (x=0.0, 0.7) have been studied out by X-ray photoelectron spectroscopy, IR spectroscopy, NMR and thermogravimetric analysis. Analysis of the infrared absorption spectra was carried out for functional groups of Zn2P2O7*5H2O and Zn1.3Mn0.7P2O7*5H2O compounds. Through correlation between the symmetric and asymmetric stretching vibrations of P-O-P bridge and P-O-P angle an increase of P-O-P bridge angle was established for Zn1.3Mn0.7P2O7*5H2O. Substitution of zins by manganese has little impact on the overall balance of chemical bond in the compound, which is manifested in minor changes of the core electrons binding energies.
