Abstract
UO2(SO3F)2, UO(SO3F)2, U(SO3F)4 and MU(SO3F)6, M=Mg, Zn have been prepared by reacting UO2(O2CCH3)2, U(O2CCH3)4, U(O2CCF3)4 and MU(O2CCH3)6 with HSO3F. The analysis of i.r. spectral data of UO2(SO3F)2, UO(SO3F)2 and MU(SO3F)6 shows the presence of only one type of SO3F group with reduced symmetry Cs. In U(SO3F)4, two SO3F groups are bidentate, while the other two are monodentate. A sharp band at 925 cm-1 in UO2(SO3F)2 is diagnostic of UO22+. The diffuse reflectance spectra of UO(SO3F)2, U(SO3F)4 and MU(SO3F)6 reveal hexacoordination of U(IV), while the magnetic moments of these compounds support the existence of U(IV). UO2(SO3F)2 and UO(SO3F)2 decompose thermally in a single step with the evolution of SO2F2 and formation of their respective sulphates.
