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.

Organouranium chemistry is the science exploring the properties, structure, and reactivity of organouranium compounds, which are organometallic compounds containing a carbon to uranium chemical bond. [1] The field is of some importance to the nuclear industry and of theoretical interest in organometallic chemistry.
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactively decays, usually by emitting an alpha particle.
Uranous compounds are usually unstable; they revert to the oxidised form on exposure to air. Examples of these compounds include salts such as uranium tetrachloride (UCl 4) and uranium tetrafluoride (UF 4), which are important in molten salt reactor applications, and uranium dioxide (UO 2), a common form of nuclear fuel.
Enriched uranium is a type of uranium in which the percent composition of uranium-235 (written 235 U) has been increased through the process of isotope separation.Naturally occurring uranium is composed of three major isotopes: uranium-238 (238 U with 99.2732–99.2752% natural abundance), uranium-235 (235 U, 0.7198–0.7210%), and uranium-234 (234 U, 0.0049–0.0059%).
Like many uranium glass collectors, they are especially drawn to pearline, which was created by several companies, mostly in Britain, from the end of the 19th century into the 20th.
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 ...
