The authors establish that in the interaction of solutions of uranyl nitrate containing excess HNO/sub 3/ with dimethylformamide, the compound UO/sub 2/(N)/sub 3/)/sub 2/ X 2HCON(CH/sub 3/)/sub 2/ crystallizes. An analysis of the IR spectrum of the salt indicates bidentate coordination of the NO/sup -//sub 3/ ions and a bond of the DMFA molecules to the uranium atom through the oxygen atoms. The interplane distances were calculated according to the x-ray powder patterns. The solubility of the compound was studied as a function of the composition of the liquid phase. The minimum solubility, equal to 0.013 M, is achieved at NHO/sub 3/ concentrations of about 6 M and DMFA 4-6 M. Using the electronic absorption spectra, some data were obtained on the nature of comoplex formation in solution.
