Reviewing interactions between uranyl’s oxygen atom, hydrogen, p block elements, and their effects in uranium-oxygen bond length.

Abstract

Thanks to the Cambridge Structural Database, in this thesis work has been selected several uranyl’s ion crystal structures, which share interactions between uranyl’s oxygen and block p elements, or hydrogen. These interactions belong to hydrogen bond, chalcogen and halogen bond or, in a more generic way, short contact interactions. In order to select the structures, the research fields were limited for certain elements to a value within their Van der Waals peak. It was evaluated the influence that these interactions provide to the uranyl’s ion bond length (U=Oyl) from two points of view: a) by considering the type of interacting element and b) by considering the type of donor atom in equatorial position. The data collected were also used to verify the existence of a trend that correlates the interaction length, or nature of equatorial ligands, to the uranyl’s bond length. A comparation between the IR and Raman data, provided by the original works, completes the overview. In conclusion, the main synthetic routes to achieve the structures analysed in this research were highlighted.
