Structural Features of Uranyl Hydroxylaminate and Oximate Complexes

Аннотация

On the basis of the currently available uranyl complexes with hydroxylamine and its N-substituted derivatives and oximes, the coordination modes of the ligands and structural features of such complexes have been considered with the aim of determining general trends for this new family of uranium(VI) compounds. All the uranyl oximate and hydroxylaminate complexes contain a deprotonated ligand coordinated to the central atom through the nitrogen and oxygen atoms to form a stable three-membered chelate ring. Depending on the composition, these compounds can be divided into two large groups: complexes with tris(chelate) and bis(chelate) structural moieties.
