Although the chemistry of uranium alkoxides has been widely studied, not much attention has been paid to alkoxide chemistry of transuranic elements. In 1967, Samulski and Karraker were able to isolate a few examples of transuranic alkoxides. However,

Early An(IV) complexes with N-donor ligands

Autor: März, J., Fichter, S., Patzschke, M., Kaden, P., Köhler, L., Schmidt, M., Stumpf, T.

Publikováno v: Actinides Revisited, 21.09.2022, Dresden, Deutschland

The 5f electrons of particularly the early actinides are found to participate in bonding, e.g. to organic ligands, in contrast to the strongly shielded 4f electrons of the lanthanides. Reactivity and complexation strength of such bonds are affected b
