Dimethyl sulphoxide complexes of some actinoid tetranitrates

Abstract

Complexes of some actinoid tetranitrates with dimethyl sulphoxide (dmso), M(NO3)4,xdmso [x= 6 (Th, Np, and Pu) and 3 (Th, U, Np, and Pu)] have been prepared by reactions in non-aqueous media. I.r. and Raman spectral, results are reported for these complexes together with i.r. spectra of the hexanitrato-complexes Cs2[M(NO3)6](M = Th and Np). X-Ray powder diffraction data are also presented together with details of the electronic spectra of the uranium, neptunium, and plutonium complexes.
