    • note
    • Complex 2 might adopt a dimeric structure similar to that of 1′, although a single-crystal suitable for X-ray analysis was not yet obtained. The lower THF content of the Sm(II) complex 2 as compared to that of the Yb(II) complex 1 might be due to the larger ion radius of Sm(II), which would thus more easily lead to formation of a further assembled structure through "intermolecular" metal-ligand interactions.

    • 1H NMR spectra of 3-5 did not offer any structural information, owing to the strong paramagnetic influence of the Yb-(III) ion and/or the ketyl radical species.
