Uranium compounds are compounds formed by the element uranium (U). Although uranium is a radioactive actinide , its compounds are well studied due to its long half-life and its applications. It usually forms in the +4 and +6 oxidation states , although it can also form in other oxidation states.
Uranyl nitrate is a water-soluble yellow uranium salt with the formula UO 2 (NO 3) 2 · n H 2 O.The hexa-, tri-, and dihydrates are known. [3] The compound is mainly of interest because it is an intermediate in the preparation of nuclear fuels.

The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula UO 2+ 2. It has a linear structure with short U–O bonds, indicative of the presence of multiple bonds between uranium and oxygen. Four or more ligands may be bound to the uranyl ion in
Uranyl sulfate describes a family of inorganic compounds with the formula UO 2 SO 4 (H 2 O) n. These salts consist of sulfate, the uranyl ion, and water. They are lemon-yellow solids. Uranyl sulfates are intermediates in some extraction methods used for uranium ores. [1] These compounds can also take the form of an anhydrous salt.
Uranium(IV) sulfate (U(SO 4) 2) is a water-soluble salt of uranium. It is a very toxic compound . Uranium sulfate minerals commonly are widespread around uranium bearing mine sites, where they usually form during the evaporation of acid sulfate-rich mine tailings which have been leached by oxygen-bearing waters.
Like most uranyl salts, the compound is a polymeric, each uranium(VI) center being bonded to eight O atoms. [1] Hydrolysis products of rutherfordine are also found in both the mineral and organic fractions of coal and its fly ash and is the main component of uranium in mine tailing seepage water.
Compounds M I 3 UO 4 have a defect rock-salt structure. M I 7 UO 6 structures are based on a hexagonally close-packed array of oxygen atoms. In all cases the uranium is at the centre of an octahedron of oxygen atoms. Also M III UO 4 have been recently synthesized and characterized (M III =Bi, Fe, Cr etc.). [14] [15] Few other compounds of ...
