Abstract
TiUO 5 and Ti 2UO 6 were prepared and identified by powder X-ray diffraction analysis. The oxidation states of uranium and titanium in TiUO 5 were found to be basically hexavalent and tetravalent respectively by X-ray photoelectron spectroscopy, but owing to the non-stoichiometry of this compound, a trace of paramagnetic susceptibility was also observed. In Ti 2UO 6 both uranium and titanium are in the tetravalent state according to X-ray photoelectron spectra. However, the magnetic susceptibility for Ti 2UO 6 is temperature independent with a superimposed broad peak around 25 K. Considering the structure of Ti 2UO 6, this anomalous behaviour is discussed on the basis of crystal field theory and magnetic superexchange interaction between uranium ions.
