Abstract By precipitating from an aqueous solution of Ce(SO4)2·4H2O with 40 % hydrofluoric acid obtained a nanosized powder of cerium tetrafluoride hydrate with a composition close to CeF4*0.95 H2O. According to the results of x-ray phase analysis, the crystalline phase has a cubic lattice similar to lattice of PuF4·1.6H2O. The hydrate nanopowder is characterized by XRD, TEM, 1H and 19F{1H}NMR and IR - spectroscopy. Quantum chemical calculations of the IR- spectra of models of the possible interaction of water molecules with a fluorine ions have been carried out. The temperature behavior of the CeF4*0.95 H2O powder was studied by using X-ray powder diffraction analysis up to 300 °C and thermogravimetrically up to 200 °C.
