Chemistry of fluoride complexes of uranyl (review)

Abstract

The synthesized and investigated by X-ray diffraction and thermogravimetric analyzes and IR spectroscopy fluoride complexes of uranyl, which are formed in the MF-UO₂F_2^-H₂O systems with alkali metal and ammonium cations, with protonated cations of organic bases, are systematized and discussed. For the first time, fluoride complexes of uranyl with a rubidium cation, with divalent transition metal cations, and with mixed monovalent, mono- and divalent transition metal cations have been obtained and studied. The nature of thermal decomposition for a number of synthesized complexes has been determined. The features of the manifestation of the vibrational frequencies of the U-F and UO₂²⁺ in the IR spectra of the obtained fluoride complexes of uranyl are established.
