Uranyl
·noun The radical UO2, conveniently regarded as a residue of many uranium compounds.
Uranyl
The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula . It has a linear structure with short U–O bonds, indicative of the presence of multiple bonds between uranium and oxygen.

Pentavalent Uranyl Complexes
UV is the +5 oxidation state of uranium which is found in the form of [UO2]1+. This species is known as pentavalent uranyl cation and has a low stability due to the disproportionation into tetravalent and hexavalent uranium species.

The uranyl ion is an oxycation of uranium in the oxidation state +6, with the chemical formula UO2+
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 an equatorial plane around the uranium atom. The uranyl ion forms many complexes, particularly with ligands that have oxygen donor atoms. Complexes of the uranyl ion are important in the extraction of uranium from its ores and in nuclear fuel reprocessing.
Examples of use of uranyl
1. The 2004 experiment used uranyl nitrate, a salt of natural uranium.
2. Today, we restarted work for production of AUC (Ammonium uranyl carbonate)," he said.
3. Mohammad Saeedi, deputy head of the Atomic Energy Organization of Iran, said work was resuming stage by stage‘‘ at Isfahan, starting with the unit that makes ammonium uranyl carbonate, or AUC, a component in the conversion process.
