Intercalation reactions of UTeO5 and USeO5

Abstract

New intercalation compounds of the pseudo-layered oxides Uv'Te'v05 and UV'Se'V05 have been prepared and characterised At ambient temperatures products of the type AxUM05 (x < 1, A = Li, Na, H, NH,) are formed by both host oxides with minimal structural change Magnetic susceptibility measurements confirm that Uv species are formed on intercalation Several metal oxides, MO,, where M is a transition metal (or uranium) in a high oxidation state, have tunnelled or layered structures which undergo insertion or intercalation reactions at ambient temperatures These result in the formation of products, AxMO,, in which a electropositive element A is incorporated interstitially into the host oxide with minimal

Structural investigations of UTeO4

“…The bands at 400.90 and 430.49 cm −1 of UTeO 5 correspond to 392.23 cm −1 of UTeO 4 . The assignments of the vibrational modes of UTeO 5 (Dickens et al , 1996) are given along with the observed data.…”
