Tom Bergmann: Cooperative Light-Driven Hydrodefluorination by a Ce(III)–Rh(−I) Heterobimetallic Complex
In recent years, the use of Lewis acidic metals as Z-type ligands to modulate the electronic properties of transition metal (TM) complexes has gained significant interest. However, examples for incorporation of lanthanides and especially cerium into bimetallic complexes remain scarce.

Julia Schwärecke: Ligand field analysis for lanthanoids: Why?"
To a zeroth approximation the electronic structure of lanthanoid ions in a chemical environment can be regarded as being very similar to that of the free ions. This led, falsely so, to the simplification that ligand field effects do not exist or are irrelevantly small for lanthanoids.
