Cp2LnX compounds with amide and related N-donor ligands

5 Cp2LnX compounds with amide and related N-donor ligands 

In a similar manner, treatment of Cp2LnBun (Ln = Y, Dy, Er) with iV,iV -di-f-butylcarbodiimide resulted in monoinsertion of carbodiimide into the Ln-C bond to yield the amidinate complexes 

Three equivalents of 1,3-diphenyltriazene react with 1 equiv. of the tris(cyclopentadienyl)lanthanides in the presence of pyridine to afford tris(l,3-diphenyltriazenido)(pyridine) lanthanide complexes. Single crystal X-ray determinations of bis(cyclopentadienyl)(l,3-diphenyltriazenido)(4-/-butylpyridine)erbium revealed a monomeric species with two cyclopentadienyl ligands, one bidentate 1,3-diphenyltriazenido ligand, and one 4-/-butylpyridine
