    • Alternatives to ubiquitous cyclopentadienyl systems have been pursued fervently in lanthanide chemistry. Amides have become the most successful of these alternatives owing to their ease of derivatisation and commensurate charge characteristics when associated with electropositive metals. For a review of this area see:

    • In isolation, FTIR data for lithium complexes 1-6 suggest there may be a correlation between the binding mode adopted, beit bridging or chelating, and the wavenumber of the C=N stretch. However, upon analysis of analogous absorptions for complexes 7-12 (vide infra), and consideration of the mixed tautomerisation of compounds 2 and 8, no definitive relationship between this stretch and the binding mode, or the placement of the aromatic groups to the NCN backbone, could be established
