Tetravalent actinide complexes with N,O-donor ligands: Synthesis and characterisation

A fundamental understanding of tetravalent actinides can be achieved by series of analogue coordination compounds with organic ligands bearing typical biologically relevant binding functions like N and O donors. Complex series with different actinides (Th, U, Np) or slightly modified ligands show differences in binding modes and complex geometry. Structural information can also be gained from NMR studies of the paramagnetic complexes.
