M. Fedosseev, N. A. Budantseva, M. S. Grigoriev, K. E. Guerman, J.-C. Krupa] Preparation, crystal structure and properties revealed through IR and visible absorption spectroscopy study of Np(V,VI), Pu(VI) compounds formed with pertechnetate anions are reported. Spectrophotometric study of Np(V) and Pu(VI) in NH4TcO4 aqueous solutions (TcO4- concentration ranging between 0.2-0.5M) shows only a slight interaction of NpO2+ and PuO22+-ions with pertechnetate oxoanions in solution. On the contrary, for Np(V), Np(VI) and Pu(VI) pertechnetates in solid state, changes in the spectra clearly evidence the coordination of the actinides(V,VI) with TcO4--anions. That is in agreement with Np(VI) pertechnetate X-ray structural analysis performed on a single crystal. © 2003 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Fedosseev A.
