Between Enamide and Azaallyl Structures: Novel Flexible N-Chelate Ligands in the Lanthanide Chemistry
摘要:
Novel types of hexa-1,5-diene-1,6-diamide neodymium complexes were prepared from the corresponding neodymium bromide NdBr3(THF)(3.5) with the appropriate dilithium hexa-1,5-diene-1,6-diamide reagent. The molecular structures of the new complexes revealed that the chelating hexa-1,5-diene-1,6-diamide can be bound either as an enamide or as an azaallyl-type ligand.
