"The coordination of a bis(NHC)pyridyl (NHC = N-heterocyclic carbene) ligand to d(0) fragments of group 3, lanthanide, and actinide series (M = Sc. Y, La, Sm, Lu, U, and Am) has been theoretically investigated at the DFT level," scientists writing in the journal Organometallics report.
"The influence of the pi-donation ability of the co-ligand has been emphasized by comparing the trichloro, trisamido fragments and bare ions. The coordination of the tridentate CNC ligand is dominated by the ligand → metal sigma-donations, but unprecedented N-am → C-carb ''back-bonding'' was evidenced in the trisamido complexes of La, Son, and Am," wrote L. Maron and ...
