The structure of uranyl nitrato complex with CMPO[n-Octyl(phenyl)-N, N-diisobutylcarbamoylmethylpho-sphine oxide] in solid state and in non-aqueous solvents without containing free CMPO has been studied by using IR spectrophotometer, <SUP>13</SUP>C- and <SUP>31</SUP>P-NMR. The carbonyl(<SUB>νCO</SUB>) and phosphoryl(<SUB>νPO</SUB>) stretching bands of coordinated CMPO were observed at lower wavenumber than the corresponding bands of free CMPO in both the states. The <SUP>13</SUP>C and <SUP>31</SUP>P peaks assigned to the carbonyl carbon and phosphoryl phosphine of coordinated CMPO was detected in the lower field than that of free CMPO. From these results, it was concluded that the uranyl nitrato complex with CMPO in both the states has the structure with two nitrate and one CMPO coordinated as bidentate in the equatorial plane of uranyl ion, i.e., UO<SUB>2</SUB>(NO<SUB>3</SUB>)<SUB>2</SUB>•CMPO. Furthermore, the electrochemical studies of UO<SUB>2</SUB>(NO<SUB>3</SUB>)<SUB>2</SUB>•CMPO complex in CH<SUB>3</SUB>CN have been carried out using cyclic and normal pulse voltammetric methods. It was found that the UO<SUB>2</SUB>(NO<SUB>3</SUB>)<SUB>2</SUB>•CMPO complex is reduced to U(V) complex at around -1.22V vs. Fc/Fc+ (ferrocene/ferrocenium) and that the resulting reductant is oxidized to U(VI) at around +0.04V vs. Fc/Fc+.
