This paper reports the preparation and the i. r. and visible spectra of new hydrated sulfate complexes of uranium(IV). The hydroxy‐sulfates originated from hydrolyses are also characterized. All the compounds were isolated by photochemical reduction from alcoholic solutions which were obtained by the addition of sulfuric acidified solution of uranyl sulfate to the appropriate sulfate. The i. r. spectra allow to distinguish between neutral and basic sulfates the bands of which are discussed. The oxygen environment for uranium(IV) in the sulfate solutions originates visible spectra similar to those of the uranium(IV) chloride so that it might be supposed that ligand fields have little effects on the absorption spectra in these cases.
