Actinyl chemistry across the U, Np and Pu series

The air stable uranyl and neptunyl phosphine oxide complexes act as good starting material to prepare the air and moisture sensitive phosphinimines species and show a preference for N-donor ligands. Calculations confirmed those observations and proved the UN bond to be stronger than the UO bond. To continue our investigations on transuranyl chemistry, the complexes PuO2Cl2(R3PO)2 have been synthesised as well as new amides species of NpO22+ and PuO22+ characterised by NMR spectroscopy.
