Fig. 4. The background-subtracted and normalized L-edge XANES spectra obtained from LnIII(C5H4SiMe3)3 (black traces) and [K(2.2.2-cryptand)][LnII(C5H4SiMe3)3] (pink traces) for Ln = Yb, Sm, Tm, Dy, Nd, Pr, Lu, Ho, Er, Tb and Gd. All spectra were collected at the Ln L3-edge except Nd and Pr, which were collected at the L2-edge. Peak maxima are shown in each pane. The spectra have been ordered from top to bottom based on increasing general reduction potentials.4,16 .
