Title: Isolation of U( ii ) compounds using strong donor ligands, C 5 Me 4 H and N(SiMe 3 ) 2 , including a three-coordinate U( ii ) complex

New examples of uranium in the +2 oxidation state have been isolated by reduction of Cp tet 3 U (Cp tet = C 5 Me 4 H) and U(NR 2 ) 3 (R = SiMe 3 ). Results show that more donating ligands as well as lower coordination number complexes are viable for U( ii ) and suggest new targets for An( ii ) complexes involving Np, Pu, and Am.
